Description

Connecteur rapide monobloc à encombrement réduit. One-piece quick connector with reduced overall dimensions.
La présente invention concerne un connecteur rapide destiné à être utilisé dans des circuits conducteurs de fluides sous pression pour raccorder deux éléments du circuit entre eux, tels que des conduites, ou une conduite à un organe émetteur ou récepteur d'un fluide.The present invention relates to a quick connector intended to be used in circuits conducting pressurized fluids to connect two elements of the circuit to one another, such as pipes, or a pipe to a transmitter or receiver of a fluid.
Un connecteur rapide du type connu comporte généralement un embout de raccordement avec une partie mâle et une partie femelle opposées et coaxiales à un axe longitudinal du connecteur. Chacune de ces parties est destinée à être accouplée à un des éléments à raccorder, c'est-à-dire à être emmanchée à force dans un tube pour la partie mâle (avec assemblage dents de sapin et/ou collage et/ou soudage et/ou collier de serrage) et à recevoir pour la partie femelle, l'élément à raccorder : soit l'embout d'un autre tube, soit l'embout de tout autre organe, et ce de manière amovible et verrouillable . Afin d'éviter une déconnexion accidentelle, le connecteur rapide comporte un organe de retenue, associé à la partie femelle, mobile ou déformable élastiquement entre une position de verrouillage dans laquelle l'organe de retenue coopère avec une gorge ménagée sur l'embout de l'autre tube ou pièce à raccorder pour maintenir celui-ci accouplé avec la partie femelle et une position de déverrouillage dans laquelle l'organe de retenue est dégagé de la gorge pour permettre la décon- nexion de l'élément (organe ou autre tube) concerné.A quick connector of the known type generally comprises a connection end piece with a male part and a female part opposite and coaxial with a longitudinal axis of the connector. Each of these parts is intended to be coupled to one of the elements to be connected, that is to say to be force fitted into a tube for the male part (with fir tree teeth assembly and / or bonding and / or welding and / or clamp) and to receive for the female part, the element to be connected: either the end piece of another tube, or the end piece of any other member, and this in a removable and lockable manner. In order to avoid accidental disconnection, the quick connector comprises a retaining member, associated with the female part, movable or elastically deformable between a locking position in which the retaining member cooperates with a groove formed on the end piece of the 'other tube or part to be connected to keep it coupled with the female part and an unlocked position in which the retaining member is released from the groove to allow the disconnection of the element (member or other tube) concerned.
Couramment, un organe de retenue est réalisé sous forme d'une bague rapportée dans un logement adjacent à l'orifice d'entrée de la partie femelle. La bague est maintenue dans sa position de verrouillage par un organe élastique de rappel à l'effet duquel il est nécessaire de s'opposer lors de la connexion ou de la déconnexion d'avec l'élément. Un tel organe de retenue permet une retenue efficace de la conduite en position raccordée. Toutefois, la présence de la bague sur l'embout requiert une structure relativement complexe pour fournir un logement à la bague et une opération de montage de la bague sur le connecteur, ce qui rend ce connecteur relativement coûteux.Commonly, a retaining member is produced in the form of an attached ring in a housing adjacent to the inlet orifice of the female part. The ring is held in its locking position by an elastic return member to the effect of which it is necessary to oppose when connecting or disconnecting with the element. Such a retainer allows effective retention of the pipe in the connected position. However, the presence of the ring on the endpiece requires a relatively complex structure to provide housing for the ring. and a mounting operation of the ring on the connector, which makes this connector relatively expensive.
Pour pallier cet inconvénient, il a été réalisé un connecteur rapide comportant un organe de retenue réalisé sous la forme d'une bague déformable, d'une seule pièce avec le connecteur, présentant des saillies radiales internes diamétralement opposées pour coopérer avec une collerette portée par l'élément inséré dans la partie femelle de l'embout. La bague déformable est reliée par deux pattes à la partie femelle de l'élément au niveau de l'orifice d'entrée de celui-ci de manière à s'étendre coaxialement à l'axe longitudinal du connecteur. Ainsi, le connecteur rapide comprend un minimum de pièces limitant les opérations d'assemblage et permet une retenue efficace de la conduite dans l'embout. Cependant, un tel connecteur rapide présente, du fait de la présence de la bague déformable, des dimensions transversales relativement importantes nécessitant de disposer d'un espace correspondant pour permettre son implantation dans l'installation. En outre, pour libérer la conduite de l'embout, il est nécessaire d'exercer manuellement une pression sur la bague en deux zones diamétralement opposées selon une direction perpendiculaire à celle des saillies. Une fois le connecteur installé sur le circuit, il est donc nécessaire de disposer d'un espace libre suffisant autour du connecteur pour permettre le passage de deux doigts de l'opérateur de part et d'autre du connecteur ou d'un outil approprié. Or, dans les installations comportant de tels circuits et par exemple dans le compartiment moteur des automobiles, il est fréquent que l'espace libre autour du connecteur soit particulièrement réduit. Il est alors difficile d'atteindre la bague déformable pour opérer la déconnexion et l'opérateur risque de devoir extraire en force l'élément raccordé et détériorer l'organe de retenue du connecteur. Il sera alors nécessaire de procéder au remplacement du connecteur tout entier, voire de la canalisation, sauf à laisser ce connecteur en place et courir le risque d'une déconnexion accidentelle .To overcome this drawback, a quick connector has been produced comprising a retaining member produced in the form of a deformable ring, in one piece with the connector, having diametrically opposite internal radial projections to cooperate with a flange carried by the element inserted in the female part of the nozzle. The deformable ring is connected by two tabs to the female part of the element at the level of the entry orifice thereof so as to extend coaxially to the longitudinal axis of the connector. Thus, the quick connector comprises a minimum of parts limiting assembly operations and allows effective retention of the pipe in the end piece. However, such a quick connector has, due to the presence of the deformable ring, relatively large transverse dimensions requiring the availability of a corresponding space to allow its implantation in the installation. In addition, to release the pipe from the end piece, it is necessary to manually exert pressure on the ring in two diametrically opposite zones in a direction perpendicular to that of the projections. Once the connector is installed on the circuit, it is therefore necessary to have sufficient free space around the connector to allow the passage of two operator fingers on either side of the connector or of an appropriate tool. However, in installations comprising such circuits and for example in the engine compartment of automobiles, it is frequent that the free space around the connector is particularly reduced. It is then difficult to reach the deformable ring to operate the disconnection and the operator risks having to forcefully extract the connected element and damage the connector retaining member. It will then be necessary to replace the connector whole, or even the pipe, except to leave this connector in place and run the risk of accidental disconnection.
Il existe donc un besoin non résolu de manière commode à ce jour d'un connecteur rapide, de structure simple et relativement peu coûteux, pourvu d'un moyen de retenue dont la manoeuvre peut être réalisée dans un espace réduit autour du connecteur rapide une fois celui-ci implanté dans le circuit de fluide. A cet effet, on prévoit, selon l'invention, un connecteur rapide de liaison d'au moins une conduite à un canal ménagé dans un élément comportant un embout tubulaire de raccordement divisé le long d'un axe longitudinal de cet embout en une première partie assujettie à la conduite et en une seconde partie destinée à coopérer avec le canal et un organe de retenue, interposé entre l'élément et l'embout, et déformable élastiquement entre un état de repos verrouillant la liaison de l'embout et de l'élément et un état commandé de déverrouillage de cette liaison. L'organe de retenue est en une seule pièce avec l'embout et comprend, d'une part, une lame s 'étendant de façon sensiblement parallèle à l'axe longitudinal de l'embout et radialement espacée de la seconde partie de ce dernier avec à son extrémité libre une saillie d'accrochage et, d'autre part, un élément de manoeuvre de la lame entre l'état de repos et l'état commandé comportant un levier en une seule pièce avec la lame, l'élément comportant au moins une dent d'accrochage derrière laquelle, dans le sens de l'accouplement de l'embout à cet élément, vient se loger la partie en saillie de la lame.There therefore exists a need that has not yet been conveniently solved for a quick connector, of simple structure and relatively inexpensive, provided with a retaining means, the operation of which can be carried out in a reduced space around the quick connector once the latter implanted in the fluid circuit. To this end, provision is made, according to the invention, for a quick connector for connecting at least one pipe to a channel formed in an element comprising a tubular connection end piece divided along a longitudinal axis of this end piece in a first part subject to the pipe and in a second part intended to cooperate with the channel and a retaining member, interposed between the element and the end piece, and elastically deformable between a state of rest locking the connection of the end piece and the element and a commanded state of unlocking of this link. The retaining member is in one piece with the end piece and comprises, on the one hand, a blade extending substantially parallel to the longitudinal axis of the end piece and radially spaced from the second part of the latter with at its free end a hooking projection and, on the other hand, a blade operating element between the rest state and the controlled state comprising a lever in one piece with the blade, the element comprising at least one hooking tooth behind which, in the direction of coupling of the nozzle to this element, is housed the projecting part of the blade.
Ainsi, l'organe de retenue a une structure particulièrement simple permettant sa réalisation d'une seule pièce avec l'embout, de sorte que le nombre de pièces du connecteur est limité et que sa fabrication est peu coûteuse. Du fait de l'agencement de l'élément de manoeuvre sur un côté longitudinal du connecteur, le connecteur présente un faible encombrement et l'élément de manoeuvre peut être accessible même lorsque l'espace libre autour du connecteur est réduit. En outre, la structure de l'organe de verrouillage selon l'invention permet de réaliser des connexions entre un tube avec embout et un organe quelconque qui n'est pas nécessairement de forme tubulaire comme l'impose la bague de verrouillage connue.Thus, the retaining member has a particularly simple structure allowing it to be made in one piece with the end piece, so that the number of pieces of the connector is limited and that its manufacture is inexpensive. Due to the arrangement of the operating element on a longitudinal side of the connector, the connector has a small footprint and the operating element can be accessible even when the free space around the connector is reduced. In addition, the structure of the locking member according to the invention allows connections to be made between a tube with end piece and any member which is not necessarily of tubular shape as required by the known locking ring.
Selon un mode de réalisation particulier, la lame est portée par l'embout au moyen d'une patte de rattachement implantée entre les deux parties de l'embout, le levier de commande étant formé par une prolongation de la lame au-delà de cette patte d'attachement. La structure de l'organe de retenue est alors particulièrement simple. Par ailleurs, le connecteur comporte un moyen amovible de condamnation de la manoeuvre du levier de commande. L'accouplement des éléments raccordés est alors particulièrement résistant et tout risque de déconnexion accidentelle est écarté. D'autres caractéristiques et avantages de l'invention ressortiront à la lecture de la description qui suit de modes de réalisation particuliers non limitatifs de 1 ' invention.According to a particular embodiment, the blade is carried by the endpiece by means of a connecting tab implanted between the two parts of the endpiece, the control lever being formed by an extension of the blade beyond this attachment tab. The structure of the retaining member is then particularly simple. Furthermore, the connector comprises a removable means for locking out the operation of the control lever. The coupling of the connected elements is therefore particularly resistant and any risk of accidental disconnection is eliminated. Other characteristics and advantages of the invention will emerge on reading the following description of particular non-limiting embodiments of the invention.

A deformable member, generally designated at 5, for mutual retention of an element 6 and of the connected endpiece is integral with the intermediate part 3.
L'embout 1, 2, 3 et l'organe de retenue 5 sont réalisés d'une seule pièce, par exemple par injection ou surmoulage d'une matière plastique.The end piece 1, 2, 3 and the retaining member 5 are made in one piece, for example by injection or overmolding of a plastic material.
En référence aux figures 1 à 3, et selon le premier mode de réalisation, la partie 1 de l'embout est mâle et a une surface externe pourvue, de façon connue en soi, de dents de sapin 7 annulaires, et la partie 2 est également mâle et a une surface externe présentant une gorge recevant un joint torique 8.

On notera que la lame 9 est suffisamment écartée de la surface externe de la partie 2 pour que l'embout puisse être inséré dans l'élément 6 sans que la lame 9 constitue une gêne. La distance séparant la lame 9 de la partie 2 sera ici au moins égale à l'épaisseur de la paroi à un endroit donné de l'élément 6. L'organe de retenue 5 forme un ensemble élasti- quement déformable entre un état de verrouillage dans lequel la lame et la patte d'attachement 5a sont dans un état de repos et d'autres états dans lesquels la lame et/ou la patte d'attachement sont déformées, ces autres états étant essentiellement un état transitoire lors de la connexion dans lequel la lame 9 principalement est fléchie élastiquement et un état de déverrouillage dans lequel la lame 9 est déplacée, sans être pratiquement déformée, du fait d'un fléchissement élastique de la patte d'attache- ment .It will be noted that the blade 9 is sufficiently spaced from the external surface of the part 2 so that the end piece can be inserted into the element 6 without the blade 9 constituting any discomfort. The distance separating the blade 9 from the part 2 will here be at least equal to the thickness of the wall at a given location of the element 6. The retaining member 5 forms an elastically deformable assembly between a locking state in which the blade and the attachment tab 5a are in a state of rest and other states in which the blade and / or the attachment tab are deformed, these other states being essentially a transient state upon connection in wherein the blade 9 is mainly bent elastically and an unlocked state in which the blade 9 is moved, without being practically deformed, due to an elastic bending of the attachment tab.
L'extrémité libre 10 de la lame 9 présente une saillie 12 orientée en direction de l'axe 4. La saillie 12 est destinée à coopérer, dans l'état de verrouillage de l'organe 5, avec une collerette 13 de l'élément 6 pour constituer une butée s 'opposant au désengagement de cet élément 6 et de l'embout. On notera que dans ce cas de figure l'élément 6 est un corps tubulaire (par exemple un embout monté sur un autre tube) et que n'importe quelle zone de la collerette (ou épaulement) 13 constitue une dent d'accrochage de la saillie 12 qui se loge derrière elle dans la direction de connexion.The free end 10 of the blade 9 has a projection 12 oriented in the direction of the axis 4. The projection 12 is intended to cooperate, in the locking state of the member 5, with a flange 13 of the element 6 to constitute a stop opposing the disengagement of this element 6 and the nozzle. Note that in this case the element 6 is a tubular body (for example a nozzle mounted on another tube) and that any zone of the flange (or shoulder) 13 constitutes a hooking tooth of the projection 12 which fits behind it in the connection direction.
Avantageusement, la saillie 12 présente, en bout, une rampe qui forme, en coopérant avec la collerette 13, une came de soulèvement de l'extrémité 10 lors de la connexion. La collerette pourrait présenter une surface conique du côté du tube 6 pour constituer une rampe de soulèvement de l'extrémité 10.Advantageously, the projection 12 has, at the end, a ramp which forms, by cooperating with the collar 13, a cam for lifting the end 10 during connection. The collar could have a surface conical on the side of the tube 6 to form a lifting ramp at the end 10.
L'extrémité 11 de la lame 9, opposée à l'extrémité 10, forme un levier 11 et est élargie pour former l'élément de manoeuvre de la lame 9.The end 11 of the blade 9, opposite the end 10, forms a lever 11 and is widened to form the operating element of the blade 9.
On comprend que lors de l'engagement de la conduite 6 sur l'embout 2, la saillie 12 de la lame 9 à l'état de repos rencontre la collerette 13. Du fait de l'effet de came des rampes de la saillie 12 et de la collerette 13, l'extrémité 10 est soulevée et la lame 9 se déforme élastiquement , jusqu'à ce que la collerette 13 soit passée, la lame 9 revenant alors sous l'effet de sa propre élasticité dans l'état de verrouillage dans lequel la saillie 12 constitue une butée qui, en étant au contact de la collerette 13, s'oppose au dégagement de la conduite 6 de 1 ' embout .It is understood that during the engagement of the pipe 6 on the nozzle 2, the projection 12 of the blade 9 in the rest state meets the flange 13. Due to the cam effect of the ramps of the projection 12 and of the collar 13, the end 10 is raised and the blade 9 deforms elastically, until the collar 13 has passed, the blade 9 then returning under the effect of its own elasticity in the locked state wherein the projection 12 constitutes a stop which, being in contact with the flange 13, opposes the disengagement of the pipe 6 from one end piece.
Pour découpler le tube T et la conduite 6, l'opérateur exerce une pression avec un doigt ou un outil sur l'élément de manoeuvre 11 en direction de l'axe 4, ce qui a pour effet de déformer la patte d'attachement 5a et d'amener la lame 9 dans l'état de déverrouillage dans lequel la saillie 12 est soulevée et libère axialement la collerette 13.To decouple the tube T and the pipe 6, the operator exerts pressure with a finger or a tool on the operating element 11 in the direction of the axis 4, which has the effect of deforming the attachment tab 5a and to bring the blade 9 into the unlocked state in which the projection 12 is raised and releases the collar 13 axially.
Pour sécuriser le verrouillage de la connexion, on pourra prévoir, ainsi que représenté à la figure 4, un moyen de condamnation de la manoeuvre du levier 11. Dans l'exemple représenté il s'agit d'une cale, ici une bague rigide 16, en alliage métallique ou en matière plastique, dont le diamètre interne est supérieur au diamètre externe du tube T dans laquelle est introduit l'embout 1. Une griffe 15 solidaire de l'embout et diamétralement opposée au levier de manoeuvre il assure ainsi le maintien en position de la bague rigide 16 sur le connecteur avant la mise en place de celui-ci sur le tube T. L'embout pourrait également comprendre deux griffes telles que la griffe 15 disposées selon un angle de 120° par rapport au levier de manoeuvre ou selon toute autre configuration adaptée pour assurer la maintien en position de la bague 16. On pourrait également, en l'absence de griffe 15, enfiler la bague sur le tube T avant mise en place de l'embout et faire glisser celle-ci sous le levier de manoeuvre pour condamner 1 ' actionnement de celui-ci. Ce moyen de condamnation pourrait tout aussi bien être une sorte d'anneau fendu (un cavalier) chevauchant le tube T et glissé ensuite sous le levier 11.To secure the locking of the connection, provision may be made, as shown in FIG. 4, for locking the operation of the lever 11. In the example shown, it is a shim, here a rigid ring 16 , made of metal alloy or plastic, the internal diameter of which is greater than the external diameter of the tube T into which the end piece is introduced 1. A claw 15 secured to the end piece and diametrically opposite the operating lever, it thus maintains in position of the rigid ring 16 on the connector before the latter is placed on the tube T. The end piece could also include two claws such as the claw 15 arranged at an angle of 120 ° relative to the operating lever or according to any other configuration adapted to ensure that the ring 16 is kept in position. It is also possible, in the absence of claw 15, to thread the ring onto the front tube T fitting of the end piece and sliding it under the operating lever to condemn the actuation thereof. This locking means could just as easily be a kind of split ring (a jumper) straddling the tube T and then slid under the lever 11.
La bague rigide 16 s'oppose à tout effort sur l'élément de manoeuvre 11 tendant à amener la lame 9 dans son état de déverrouillage. On comprendra que la bague rigide 16 ne s'oppose pas à la connexion de l'élément 6 sur la partie 2, la lame 9 restant libre de se déformer (état transitoire) .The rigid ring 16 opposes any force on the operating element 11 tending to bring the blade 9 in its unlocked state. It will be understood that the rigid ring 16 does not oppose the connection of the element 6 on the part 2, the blade 9 remaining free to deform (transient state).
On constate à la figure 4 que l'élément 6 est ici un embout tubulaire et que la saillie 12 ne coopère plus avec une collerette mais avec une simple dent d'accrochage 13a.It can be seen in FIG. 4 that the element 6 is here a tubular end piece and that the projection 12 no longer cooperates with a flange but with a simple hooking tooth 13a.
Pour extraire l'embout de la conduite 6, l'opérateur retire la bague rigide 16 en la faisant glisser le long de l'extrémité de l'élément reçue autour de cet embout 1 puis appuie avec un doigt ou un outil sur l'élément de manoeuvre 11 pour amener la lame 9 dans son état de déverrouillage. Cette figure 4 veut illustrer le fait que l'invention n'est pas limitée à une connexion de deux corps tubulaires. Elle s'applique à la connexion d'un tube avec un embout selon l'invention et d'un corps quelconque pourvu d'un canal interne C pouvant recevoir l'embout par l'une de ses faces.To extract the end piece from line 6, the operator removes the rigid ring 16 by sliding it along the end of the element received around this end piece 1 then presses with a finger or a tool on the element maneuver 11 to bring the blade 9 in its unlocked state. This Figure 4 illustrates the fact that the invention is not limited to a connection of two tubular bodies. It applies to the connection of a tube with a nozzle according to the invention and of any body provided with an internal channel C which can receive the nozzle by one of its faces.
Les éléments identiques ou analogues porteront dans la suite de la description une référence numérique identique . Aux figures 5 et 6, on peut voir un connecteur selon un deuxième mode de réalisation.Identical or analogous elements will bear an identical reference in the following description. In Figures 5 and 6, we can see a connector according to a second embodiment.
L'organe de retenue 5 comprend, comme précédemment, une lame 9. La lame 9 a une extrémité solidaire de la partie intermédiaire 3 de l'embout au moyen d'une patte d'attachement 5a de manière à s'étendre en porte-à-faux par rapport à cette partie intermédiaire 3, parallèlement à l'axe longitudinal 4.The retaining member 5 comprises, as before, a blade 9. The blade 9 has one end secured to the intermediate part 3 of the endpiece by means of an attachment tab 5a so as to extend in carrier overhang relative to this intermediate part 3, parallel to the longitudinal axis 4.
La lame 9 a une extrémité libre 10 qui comporte une saillie 12 destinée à coopérer avec la collerette 13 de la conduite 6.The blade 9 has a free end 10 which has a projection 12 intended to cooperate with the flange 13 of the pipe 6.
Le connecteur comprend ici aussi un moyen de manoeuvre lia de la lame, formant un poussoir situé à l'opposé diamétral de la saillie 12 par rapport à l'axe 4 et raccordé à l'extrémité 10 de la lame 5 qui est alors elle-même son levier de manoeuvre, par l'intermédiaire d'une patte 19 de contournement de l'embout. La patte 19 est écartée de l'embout de manière à ne pas gêner l'introduction de celui-ci dans la conduite tubulaire 6 et a donc un rayon supérieur au rayon externe de la conduite 6. On comprend qu'une pression sur l'élément de manoeuvre lia en direction de l'axe 4 amène la lame 9 en état de déverrouillage. On notera ici que, contrairement aux exemples de réalisation précédents, l'état transitoire de l'organe de retenue et son état de déverrouillage sont atteints par des déformations semblables, à savoir une flexion de la lame 9 par exemple.The connector here also includes a means of operating 11a of the blade, forming a pusher situated at the diametric opposite of the projection 12 with respect to the axis 4 and connected to the end 10 of the blade 5 which is then itself even its operating lever, by means of a tab 19 for bypassing the end piece. The tab 19 is spaced from the end piece so as not to hinder the introduction of the latter into the tubular pipe 6 and therefore has a radius greater than the external radius of the pipe 6. It is understood that a pressure on the operating element 11a in the direction of the axis 4 brings the blade 9 in the unlocked state. It will be noted here that, unlike the previous embodiments, the transient state of the retaining member and its unlocking state are achieved by similar deformations, namely a bending of the blade 9 for example.
Selon un troisième mode de réalisation, et en référence aux figures 7 et 8 , on peut voir un connecteur rapide analogue à celui représenté à la figure 4 et décrit précédemment.According to a third embodiment, and with reference to Figures 7 and 8, we can see a quick connector similar to that shown in Figure 4 and described above.
Dans ce mode de réalisation et contrairement aux autres précédemment décrits, la saillie 12 n'est pas tournée vers l'axe 4 mais vers l'extérieur.In this embodiment and unlike the others previously described, the projection 12 is not turned towards the axis 4 but towards the outside.
L'élément 6 comprend alors un logement longitudi- nale 17 débouchant dans une encoche 18 définissant une dent d'accrochage 13b. La dent 13b peut être également un élément rapporté sur la conduite et s 'étendant dans l'encoche 18.The element 6 then comprises a longitudinal housing 17 opening into a notch 18 defining a tooth attachment 13b. The tooth 13b can also be an element attached to the pipe and extending into the notch 18.
Lors de la connexion, la lame 9 est introduite dans le logement 17 et est forcée dans son état de déverrouillage. La lame 9 est glissée dans le logement 17 jusqu'à ce que la saillie 12 s'engage dans l'encoche 18, ce qui entraîne le retour de la lame 9 dans son état de repos donc de verrouillage, la saillie 12 coopérant alors avec la dent 13b et s 'opposant à toute extraction ultérieure de l'embout hors de l'élément 6.Upon connection, the blade 9 is inserted into the housing 17 and is forced into its unlocked state. The blade 9 is slid into the housing 17 until the projection 12 engages in the notch 18, which causes the blade 9 to return to its resting and therefore locking state, the projection 12 then cooperating with the tooth 13b and opposing any subsequent extraction of the end piece from the element 6.
On comprend que pour amener la lame 9 dans son état de déverrouillage, il est nécessaire d'exercer sur l'élément de manoeuvre 11 (levier) un effort l'écartant de l'axe 4 de manière à abaisser l'extrémité 10.It will be understood that in order to bring the blade 9 into its unlocked state, it is necessary to exert on the operating element 11 (lever) a force moving it away from the axis 4 so as to lower the end 10.
Afin de sécuriser le verrouillage, une bague rigide 16 est disposée autour de l'élément de manoeuvre 11 et de la patte 15 pour s'opposer à la manoeuvre du levier 11. Aux figures 9 et 10, on a représenté un connecteur selon un quatrième mode de réalisation, dans lequel la partie 1 de l'embout est mâle tandis que la partie 2 est une partie femelle dans laquelle est introduite une conduite 6 (ou un embout) présentant extérieurement une collerette annulaire 13.In order to secure the locking, a rigid ring 16 is arranged around the operating element 11 and the lug 15 to oppose the operation of the lever 11. In FIGS. 9 and 10, a connector is shown according to a fourth embodiment, in which the part 1 of the end piece is male while the part 2 is a female part in which is introduced a pipe 6 (or an end piece) having an annular collar 13 on the outside.
L'organe de retenue 5 a une structure analogue à celle décrite en relation avec les figures 1 à 3. Cependant, dans ce mode de réalisation l'extrémité libre 10 de la lame 9 s'étend au-delà de la partie 2 de l'embout pour que la saillie 12 puisse coopérer avec la collerette annulaire 13 s 'étendant à l'extérieur de cette partie 2.The retaining member 5 has a structure similar to that described in connection with Figures 1 to 3. However, in this embodiment the free end 10 of the blade 9 extends beyond the part 2 of the end piece so that the projection 12 can cooperate with the annular collar 13 extending outside of this part 2.
Bien entendu l'invention n'est pas limitée au mode de réalisation décrit et on peut y apporter des variantes de réalisation sans sortir du cadre de l'inven- tion tel que défini par les revendications. Of course, the invention is not limited to the embodiment described and it is possible to make variant embodiments without departing from the scope of the invention as defined by the claims.
