Members), and the respective pipes 1 and 2 are fixed to the fixing member 3 by a resin clamp 5 described in detail below.

The resin clamp 5 is connected to each of the pipes 1 and 2.
1. A branch portion 7 is provided at a substantially right angle so as to intersect with each of the pipes 1 and 2 with respect to an intermediate portion in the longitudinal direction of a base portion 6 extending in the direction of arrangement (vertical direction in FIG. 1). A concave portion 8 capable of fitting and locking one of the pipes 1 is provided in the middle portion of the base portion 6.
A first grip portion 9 that opens toward one end side of the base portion 6 is provided, and an intermediate portion between the other end of the base portion 6 and the base end of the branch portion 7,
A second grip portion 11 is provided in which a concave portion 10 capable of fitting and locking the other pipe 2 is opened toward the tip side of the branch portion 7.

In the illustrated example, the first gripping portion 9
Is intended for the pipe 1 having a relatively small diameter, the recess 8
Is provided with a pedestal portion 12 for supporting the lower surface of the pipe 1, and both sides of the concave portion 8 are provided with a holding portion 13 for holding the side surface of the pipe 1. Further, an opening side end of the concave portion 8 is provided. The portion is provided with a hook-shaped locking portion 14 which is expanded when the pipe 1 is fitted and allows passage of the pipe 1 and holds the fitted pipe 1 so as not to be pulled out.

Since the second grip portion 11 is intended for the pipe 2 having a diameter larger than that of the one pipe 1, the lower surface of the pipe 2 is supported by the bottom surface of the recess 10. With respect to the other configuration, the pressing portion 15 and the locking portion 16 are provided as in the case of the first grip portion 9 described above.

Further, in the resin clamp 5, the grip portions 9 and 11 are provided at both longitudinal ends of the base portion 6.
Positioning means for fitting the pipes 1 and 2 into the recesses 8 and 10 of the pipes 1 and 2 are fitted in the through-holes 4 respectively, and the through-holes 4 are provided at both ends of the branch portion 7 in the longitudinal direction. On the other hand, there is provided a locking means capable of locking so as not to be pulled out.

The positioning means is composed of arcuate reinforcing ribs 17 and 18 projecting rearward at both end positions in the longitudinal direction of the base 6, and each of the reinforcing ribs 17 and 18 is the above-mentioned. The fixing member 3 is adapted to be internally fitted partially along the edge of the through-hole 4 at the upper and lower positions.

The locking means includes a first locking claw 19 and a backing plate 20, a second locking claw 21 and a backing plate 22 respectively provided at both end positions in the longitudinal direction of the branch portion 7. It is composed by.

The first locking claw 19 located on the base end side of the branch portion 7 is provided so as to project rearward so that the front end can be locked to the rear surface of the fixing member 3, First patch 2
0 contacts the front surface of the fixing member 3 when the tip of the first locking claw 19 is locked to the rear surface of the fixing member 3.

On the other hand, the second locking claw 21 located on the tip end side of the branch portion 7 is provided so as to project rearward and then folded back to the front to lock the tip end to the edge portion of the through hole 4. The second contact plate 22 is provided with the second locking claw 2
When the front end of 1 is locked to the rear surface of the fixing member 3, it comes into contact with the front surface of the fixing member 3.

Here, the tip of the second engaging claw 21 is
The second contact plate 22 is formed so as not to hide the tip of the second locking claw 21 when it is locked to the through hole 4 and can be seen from the assembly side. .

Then, the pair of pipes 1 and 2 arranged through the through hole 4 opened in the fixing member 3 is connected to the fixing member 3.
When fixing to, the one clamp 1 is fitted and locked in the recess 8 of the first grip portion 9, and then the resin clamp 5 is rotated about the one pipe 1 to rotate the other pipe 2. The second grip 11
It is fitted and locked in the concave portion 10 of.

At this time, for example, if two grips are arranged in parallel in the same direction to fix the pair of pipes to the fixing member, the pipes must be fitted to the grips at the same time. However, both grips are pushed out at the same time and interfere with each other, which makes it extremely difficult to fit the pipe to each grip, but in the present embodiment,
The first and second grips 9, 11 are recesses 8, 10 of each other.
Since the opening direction of the pipe 1 is shifted substantially at a right angle, even if the pipe 1 is fitted and locked in advance of the first grip portion 9, the pipe 2 can be fitted to the second grip portion 11 of the other side. The workability is extremely good without any influence that hinders the fitting and locking.

Next, the resin clamp 5 is slid in the longitudinal direction of each of the pipes 1 and 2 and moved to the through hole 4 of the fixing member 3, and the first locking claw 19 is inserted into the through hole 4 to fix the tip. The reinforcing ribs 17 and 18 are partially fitted into the edge portions of the through hole 4 at the upper and lower positions to perform positioning, and then the second locking claw 21 is inserted into the through hole. When it is bent inside 4 and passes through the through-hole 4,
The second locking claw 21 is restored to its original position after passing through the through hole 4, and the front end thereof is the rear surface of the fixing member 3 and the through hole 4.
The first and second contact plates 20 and 22 are brought into contact with the front surface of the fixing member 3 so as to prevent the resin clamp 5 from being pulled out from the through hole 4.

At this time, the locked state of the resin clamp 5 with respect to the through hole 4 can be confirmed by visually recognizing the tip of the second locking claw 21 from the assembly side.

Therefore, according to the above-described embodiment, the pair of pipes 1 and 2 can be fixed to the fixing member 3 only by the integrally molded resin clamp 5 without the need for fastening bolts or the like. Since it can be greatly reduced, workability can be greatly improved, and moreover, the number of parts is only one, so that the cost can be greatly reduced.

Furthermore, since the engagement state of the resin clamp 5 with respect to the through hole 4 can be visually recognized from the assembly side,
It is possible to reliably prevent assembly failure and the like.

The resin clamp of the present invention is not limited to the above-mentioned embodiment, and the long member may be a harness, a cable or the like other than the pipe, the first gripping portion and the first gripping portion. It is needless to say that the structures of the second grip portion, the positioning means, and the locking means are not limited to the illustrated example, and that various modifications can be made without departing from the scope of the present invention.
