Abstract

A self-locking clamp has a handle which locks to a non-rotating member if the handle starts to turn while in clamping use. The clamp has a retractable collar which is splined to the handle and is biased toward locking engagement with a sleeve that in turn seats against the member to be clamped. The collar can be held retracted from the sleeve for tightening and loosening the clamp.
