ABSTRACT OF THE DISCLOSURE A clamp for handling slabs formed of an assembly of loose concrete blocks has jaws engaging opposite sides of the slab, one of the jaws forming the shorter arm of a lever providing substantial mechanical advantage, the longer arm being moved to a position in which it locks the jaw by almost straightening a toggle linkage. A lifting force may be applied to the clamp through the toggle linkage so as to generate clamping forces, and a latch may be provided to prevent the linkage from straightening, thus allowing the clamp to be lifted from a slab without clamping the slab. The clamp enables the slab to be clamped sufficiently powerfully to lock the blocks together.
