A clamp is disclosed which has a clamp block provided with a clamp surface for engaging a mould, die or the like. The clamp has a wedging member engageable with the clamp block and a rod receivable in a bore in the block. The rod is normally biased out of the bore so that a piston and cylinder assembly can be actuated so that the piston moves the rod and wedging member and also the clamp block to a position adjacent the mould, die or the like, whereupon continued movement of the piston forces the rod into the bore and the wedge member under the clamp block to pivot the clamp block into clamping engagement with the mould, die or the like.
