A toggle clamp having first and second clamping members pivotally connected together for receiving objects to be clamped therebetween; a handle pivotally mounted with respect to one of the clamping members; a bail including a force generating member where the bail is so mounted with respect to the handle that upon movement of the handle from a first position to a second position, the force generating member is moved to a first position to generate a force for clamping the objects together with a first clamping force; and, a member, upon weakening or failure of the force generating means, which permits movement of the force generating member to a second position where the objects remain clamped together with a force less than that of the first clamping force whereby a fail-safe operation is provided.
