ABSTRACT:
A retention clamp includes a shaft having a stop member and a first threaded portion, the first threaded portion including a left hand thread. A clamping member is threadably connected to the first threaded portion. A biasing member positioned between the stop member and the clamping member transfers a rotational force applied to the shaft to the clamping member to rotate the clamping member into an engagement position. An indexing member can be slidably received over the first threaded portion and positioned between the stop member and the clamping member. The indexing member is frictionally engageable with the clamping member so indexing member rotation rotates the clamping member. Both the indexing member and the clamping member can include meshable ratchet teeth to assist clamping member rotation. Legs extending transversely from the biasing member can positively engage the stop portion and the indexing member.
