Abstract
Abstract A clip for releasable attachment to a stud having a screw thread or annular ribs comprises a mount, which is elliptical in cross-section and has transverse flanges on its long sides to engage the thread or ribs of the stud. Squeezing the mount by applying pressure onto the ends of its major axis forces the flanges apart and releases the clip. Such a deformation of the mount is checked by abutments at opposite ends of its major axis.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
166 words
A retaining clip for secure engagement with a stud having a screw thread or annular ribs, comprising a mount of resilient material provided with inwardly directed transverse flanges for engagement with the thread or ribs of the stud when the clip is pushed down onto it, characterized in that said mount is oblong as viewed in cross-section at right angles to the axis of a stud on which it is assembled, said flanges extending from the long sides of the mount at opposite ends of its minor axis, said mount further including abutments extending inwardly therefrom at opposite ends of its major axis, said mount being deformable in response to pressure applied to the ends of its major axis such that said flanges are forced apart to thereby release them from the thread or ribs of the stud, and the abutments being effective to ensure the position of the mount in which said flanges are in engagement with the stud, and limit deformation of said mount.
Claim 2
Dependent Claim
166 words
A retaining clip for secure engagement with a stud having a screw thread or annular ribs, comprising a mount of resilient material provided with inwardly directed transverse flanges for engagement with the thread or ribs of the stud when the clip is pushed down onto it, characterized in that said mount is oblong as viewed in cross-section at right angles to the axis of a stud on which it is assembled, said flanges extending from the long sides of the mount at opposite ends of its minor axis, said mount further including abutments extending inwardly therefrom at opposite ends of its major axis, said mount being deformable in response to pressure applied to the ends of its major axis such that said flanges are forced apart to thereby release them from the thread or ribs of the stud, and the abutments being effective to ensure the position of the mount in which said flanges are in engagement with the stud, and limit deformation of said mount.
Claim 3
Dependent Claim
37 words
A clip according claim 1, characterized in that said flanges extend in arch form over a central portion of said mount over approximately the same length as the thickness of the stud onto which it is engaged.
Claim 4
Dependent Claim
36 words
A clip according to claim 2 wherein each said abutments comprises a face inclined inwardly with respect to the axis of the stud and terminating at a shorter face disposed substantially parallel of the stud axis.
