Embodiments of the present invention will be described below. FIG. 1 is a configuration diagram showing a wire harness clip. This clip is constituted by a combination of a clip body 10 made of resin and a spring clip 20 made of metal. As for the clip body 10, a pair of leg pieces 1 coupled so as to form a U-shape as a whole shape.
2 and a flat harness holding portion 18 shown in FIG. 1 (A) are integrally formed. On the other hand, the spring clip 20 is incorporated inside the two leg pieces 12, and the spring clip 20 is joined so as to have a U-shape as a whole as is clear from FIG. 1 (B). A pair of holding pieces 22 are provided.

FIG. 2 is a plan view of the spring clip 20, FIG. 3 is a front view of FIG. 2, FIG. 4 is a left side view of FIG. 2, and FIG. 5 is a right side view of FIG. 6 is a plan view seen from the direction of arrow A in FIG. 3, FIG. 7 is a plan view also seen from the direction of arrow B in FIG. 3, FIG. 8 is an external perspective view of the spring clip 20,
FIG. 9 is a perspective view showing a part of the spring clip 20 in a cutaway manner. As shown in these drawings, locking claws 26 are integrally formed on both holding pieces 22 of the spring clip 20 in a state where the locking claws 26 are individually cut and raised inward.

FIG. 6 shows the distal ends of the two locking claws 26.
As shown in FIG. 7 or FIG. 9, comb-shaped engaging teeth 28 are respectively formed. Then, the engagement teeth 28 of the both locking claws 26
Are set so that their teeth and grooves correspond to each other, and as a result, both engaging teeth 28 are butted in an engaged state. A notch-shaped engaging groove 24 is formed on one of the edges of the holding pieces 22 of the spring clip 20. However, the engagement grooves 24 may be formed on both side edges of both the holding pieces 22 respectively.

As shown in FIGS. 1 (A) and 1 (B), blocking pieces 14 are integrally formed at the distal ends of the two leg pieces 12 on the open side of the clip body 10, respectively, inward. These blocking pieces 14 are positioned so as to cover both locking claws 26 of the spring clip 20 from the outside thereof, and a slight gap is provided between the tips of the blocking pieces 14. .

On the inner surfaces of both leg pieces 12 of the clip body 10, engaging portions 16 which can be engaged with the engaging grooves 24 of the spring clip 20, respectively, are formed. Further, the distal end portions 16a of the both engaging portions 16 are engaged with the inside of the both holding pieces 22 of the spring clip 20 when the engaging portion 16 and the engaging groove 24 are engaged as shown in FIG. It is supposed to.

The clip body 10 and the spring clip 20
Naturally, the spring clips 2
0 is attached to the inside of both blocking pieces 14 of the clip body 10 with respect to the inside of both leg pieces 12 of the clip body 10.
Is assembled from the side so that the locking claw 26 is located. As a result, the engaging portion 16 of the clip body 10 and the engaging groove 24 of the spring clip 20 are engaged as described above. When the engagement grooves 24 are formed on both side edges of the both holding pieces 22, it is possible to eliminate the directionality when assembling the spring clip 20 to the clip body 10.

The clip having the above configuration is attached to the wire harness 30 by winding the harness holding portion 18 of the clip body 10 around the outer periphery of the wire harness 30 with a tape 32 as shown in FIG. Clips are attached to the wire harness 30 at a plurality of predetermined locations along the length direction.

The wire harness 30 usually has a branch line (electric wire) at both ends and in the middle.
Therefore, during transportation of the wire harness 30, for example,
As shown in FIG. 10, one or a plurality of electric wires 34 may try to enter between the leg pieces 12 of the clip body 10. In such a case, even if the electric wire 34 passes between the two blocking pieces 14 of the clip body 10, the two locking claws 26 of the spring clip 20 abutted in a state where the engaging teeth 28 are engaged with each other. The electric wire 34 is reliably received. As a result, the electric wire 34 is prevented from biting into both the holding pieces 22 of the spring clip 20, and troubles such as damage to the film of the electric wire 34 or disconnection can be solved.

When wiring the wire harness 30 to a vehicle body or the like, a rib (not shown) of a clip attaching member on the body side pushes both locking claws 26 of the spring clip 20 from an opening of the clip body 10. It is inserted between both holding pieces 22 while opening. As a result, both locking claws 26 are locked to the ribs of the clip attaching member, and the clip body 1 is
0 is held on the clip attaching member side, and as a result, the wire harness 30 is held in a predetermined wiring state.

As shown in FIG. 11, both blocking pieces 14 of the clip body 10 may also be formed in a state where their leading ends abut each other. Thus, the above-described biting of the electric wire 34 is prevented by both the blocking piece 14 of the clip body 10 and the locking claw 26 of the spring clip 20. However, when the rib of the clip attaching member is inserted from the opening of the clip body 10 as described above, resistance occurs in two steps, but troubles such as film damage due to biting of the electric wire can be more reliably prevented.
