ABSTRACT:
A quick release clamp which comprises a U-shaped frame formed by two stampings spaced apart and held together in a unitary structure by means of spacers and rivets. In one arm of the frame, a screw block is anchored in which an elongated screw member is threaded and has on its inner end a clamping face. In the opposite arm a similar elongated threaded member is threaded through a block and has on its end a clamping face which is apposed to the first clamping face. In this latter case the block into which the elongated screw member is threaded is pivoted in the frame so that the clamping face can be swung away from alignment with the other clamping face.
