A clamp (10) is provided that has a pair of clamp bodies (12) which each hav e an inner surface (20). The inner surfaces (20) of each clamp body (12) are oriented to face one another in a spaced parallel relationship. A pair of parallel scissors linkages (36) are coupled to the device that operate to mo ve the clamp bodies in parallel relation relative to one another. A threaded ro d (92) is coupled to the pair of scissors linkage (36) between the clamp bodie s (12) and is oriented with its axis of rotation parallel to the inner surface s (20) of the clamp bodies (12). By operation of the rod (92), the device may be used as either a clamping device or an expansion device.
