Abstract

A clip for attaching cylindrical components such as wires or tubes to a supporting plate has a sleeve (1) to receive a fastening screw between component retaining members (2). One end (5) of the sleeve is resilient and threaded internally so as to form a snap-on connection with the screw when the sleeve is pushed over the screw shank. Resilient webs (9) engage the supporting plate surface and their resilient range (f) is at least equal to the pitch (s) of the screw thread. <IMAGE>

Description

SPECIFICATION Retaining Clip for Fastening Cylindrical Components onto a Supporting Plate The invention relates to a retaining clip for fastening preferably cylindrical components, such as pipes, tubes, cables or the like, onto a supporting plate, by means of a threaded bolt which is welded or otherwise fixed to the plate.

The clip substantially comprises a fastening sleeve adapted to be pushed onto the threaded bolt, and supporting members located on either side of the sleeve and engaging around the components with elastic retaining arms.

Retaining clips of this type are normally fixed by a nut which bears on the edge of the fastening sleeve. This fastening method does indeed allow faulty clips to be exchanged at any time; however, it is found unsatisfactory particularly in vehicle construction, since it takes a considerable time to screw on an tighten the nuts.

According to the present invention, a retaining clip of this type includes a fastening sleeve which has a portion adapted to spring open, with a screw thread or parts thereof on an inner wall, and a bearing side of the sleeve is provided with laterally projecting spring webs, the spring part of which is at least equal to the pitch of the thread. A clip of this type can easily be pressed onto the threaded bolt by applying a justifiable amount of force and, if necessary, turned downwardly by the bolt. To obtain the stablest possible mounting, the supporting webs are desirably attached to the ends of the clip approximately below the retaining members.

For reasons of deformation only one thread is provided in the fastening sleeve proposed.

However, it is conceivable and possible to make a sleeve with two or more threads, provided that each thread comprises individual segments with gaps, and that the gaps in one thread are located exactly in front of or behind the segments of the other thread-as seen axially of the sleeve-and are of the same size as those in the other thread.

An embodiment of the invention is illustrated in the accompanying drawings, in which:~ Figure 1 shows a retaining clip in the mounted state Figure 2 shows the retaining clip in a largerscale side elevation with a partial cross-section through the right half and Figure 3 is a plan view of the same clip.

The retaining clip of hard, elastic, plastics substantially comprises a fastening sleeve 1 with retaining members 2 attached at both sides. The members 2 are provided to retain preferably cylindrical components 3 such as pipes, tubes, cables or the like and are equipped with elastic retaining arms 4 which engage around these components.

In its bearing region the sleeve 1 is solidly joined to the retaining members 2, to form an integral body. A portion 5 of the sleeve adapted to spring resiliently open extends beyond the solid body. The portion 5 of the sleeve is provided with an inwardly projecting screw thread 6. The thread 6 has the same pitch and depth of thread as a threaded bolt 7, which is welded or otherwise fixed onto a supporting plate 8 to which the clip is to be attached. The threaded bolt 7 is at least one pitch longer than the length of the sleeve 1.

The retaining clip also has spring webs 9 projecting laterally at the bearing side 10. Their deflection range fis at least equal to the pitch s of the screw thread 6.

The retaining clip is mounted simply by pushing it down onto the threaded bolt 7 welded onto the supporting plate, with simultaneous bulging of the thread 6 in the portion 5 adapted to spring open, until the spring webs 9 of the clip lie firmly against the base of the supporting plate 8 and the thread 6 snaps into a corresponding thread groove in the bolt 7. The clip is thus ready to receive the pipes, tubes or the like provided for retention, without any further assembly work.

Claims

1. A retaining clip for fastening components onto a supporting plate by means of a threaded bolt which is fixed to the supporting plate, comprising a fastening sleeve to be pushed onto the threaded bolt, and retaining members located on the sleeve with elastic retaining arms to engage around the components wherein the fastening sleeve has a portion adapted to spring open, with a screw thread or parts thereof on its inner wall and is provided with laterally projecting resilient webs to engage the supporting plate the deflection range of the webs being at least equal to the pitch of the screw thread.

2. A clip according to claim 1 wherein the sleeve is located between two said retaining members.

3. A clip according to claim 2, wherein the supporting webs 9 are mounted at two ends of the clip, and below the retaining members.

4. A clip according to any of the preceding claims of hard resilient plastics material.

5. A retaining clip for fastening components to a supporting plate constructed and arranged substantially as hereinbefore described and shown in the accompanying drawings.
