## Abstract

A twist lock socket clip employs a cam over member for engagement and locking of a socket for storage or transport. A post of the clip receives the socket bore thereover and upon twisting of the socket, a cam over member depresses from engagement with the walls of the socket bore, and upon continued twisting, the cam over member relaxes and secures the socket by interaction of the socket bore detent and corresponding members on cam over arms.

## Claims

### Claim 1

A single component socket holding member, for providing cam action engagement of a socket, comprising:
a socket receiving post member for a bore portion of the socket thereon, said socket receiving post member having an axis for aligning with said bore portion;
a socket wall engaging cam over member positioned on said post member, having a flexing portion engaged with said socket receiving post member along an extent thereof and free from engagement with said socket receiving post in a region other than along said extent thereof, said cam over member having a socket detent engaging member thereon, said flexing portion having an open space defined in back of an inner oriented face thereof relative to said axis of the socket receiving post member, adapted for enabling flexing inwardly and outwardly of said flexing portion substantially perpendicular to said axis and adapted for substantially not flexing along a direction parallel to said axis.

### Claim 2 (depends on 1)

The single component socket holding member according to claim 1, wherein said cam over member is adapted for compression during an engaging step of attaching the socket and for release from said compression when at an engaged position with the socket.

### Claim 3 (depends on 1)

The single component socket holding member according to claim 1, wherein said socket receiving post member and said cam over member are formed from a plastic.

### Claim 4 (depends on 1)

The single component socket holding member according to claim 1, wherein said socket receiving post member and said cam over member are formed from a metal.

### Claim 5 (depends on 1)

The single component socket holding member according to claim 1, further comprising an engaging shoulder portion for defining a stop position when the socket is fully engaged to the clip.

### Claim 6 (depends on 1)

The single component socket holding member according to claim 1, wherein said region is defined spaced away from an upper portion and a lower portion of said socket receiving post member.
