Abstract

Selon l'invention, un élément métallique travaillé à la presse (2) est placé sur la périphérie extérieure d'un composant moulé à base de résine (1) placé du côté intérieur d'un élément de fixation (A) et des parties saillantes de fermeture (2a, 2b) faisant saillie d'un côté intérieur formé à l'extrémité dudit composant travaillé à la presse peuvent venir en prise avec le composant moulé à base de résine de manière à empêcher le composant moulé à base de résine de sortir du composant, et un moyen de blocage de rotation (3) est formé sur le composant moulé à base de résine et sur le composant travaillé à la presse de manière à solidariser les deux dans une direction périphérique, permettant ainsi la fixation aux parties de filetage extérieures (B2, B4) d'un raccord de tuyau (B). Ainsi, le poids est diminué alors qu'une détérioration est empêchée par augmentation de la dureté de surface de l'élément de fixation et une pluralité de spécifications de filetages peut être satisfaite par le seul changement d'un composant moulé à base de résine.
