Patent ID: 7082991

Claim:
A self-centering, spring retaining system comprising: an elongated slip body having wall engaging teeth proximate a first end and a slip foot at a second end; said slip body further including means defining a spring receiving groove in between said slip foot and said wall engaging teeth; said slip body further including means defining a tab receiving slot within said slip body and adjacent said means defining a spring receiving groove, whereby said slot is connected to and in communication with said spring receiving groove; a spring having an elongate body extending in a first direction along said spring receiving groove and dimensioned to be received within said spring receiving groove; said spring further including a spring retaining tab projecting outwardly from a central portion of said elongate body, whereby when said spring elongate body is received within said spring receiving groove, said spring retaining tab is retained within said tab receiving slot to center said spring about said slip body and prevent rotational movement of said spring and to prevent said spring from sliding within said groove in said first direction.
