## Abstract

Mounting apparatus for retaining a cylindrical member with respect to a first member by providing a circumferential groove only part way around the cylindrical member to extend through the aperture in the first member and providing an externally threaded clip member having an internal cavity to fit over the end of the cylindrical member with circumferential convex inwardly extending ridges on the clip member fitting within the grooves on the cylindrical member preventing rotation of the clip member and a nut member internally threaded to cooperate with the clip member in holding the cylindrical member within the aperture of the first member.

## Claims

### Claim 1

A retaining assembly for use in mounting on a first member having a cylindrical aperture therein comprising:
a cylindrical member sized to extend through the aperture in the first member, said cylindrical member having a surface groove only part way around said cylindrical member near one end thereof to form abutments where the groove ends;
an externally threaded one-piece clip member having an inner cavity sized to snap over the end of said cylindrical member, an inner surface of the cavity having a convex partially circumferential ridge extending radially inwardly into the cavity and adapted to fit within the groove on said cylindrical member upon insertion of said cylindrical member into the cavity of said clip member to hold said clip member on the end of said cylindrical member, the ridge having an end portion which cooperates with the abutments to prevent the clip member from rotating with respect to said cylindrical members; and
a nut member internally threaded to cooperate with the external threading of said clip member and operable to be tightened against the first member to secure said cylindrical member with respect to the first member.

### Claim 2 (depends on 1)

An Assembly according to claim 1 wherein the partially circumferential groove is formed in two parts each part way around said cylindrical member to form two abutments where each of the parts end.

### Claim 3 (depends on 1)

An assembly according to claim 1 wherein the partially circumferential ridge in the cavity of said clip member extend part way around the circumference to substantially the same extent that the circumferential grooves in said cylindrical member extend and form two ends where the ridges stop, the ends cooperating with the abutments to prevent rotation of the clip member with respect to the cylindrical member.

### Claim 4 (depends on 1)

An assembly according to claim 1 wherein said clip member also has a pair of longitudinally extending cut-outs extending into the cavity thereof to increase the flexibility of said clip member and facilitate a snap insertion of said cylindrical member into the cavity of said clip member.
