A clamp (1) comprises first and second clamping means (2, 3) each of which comprises a first clamping portion (4) and a second clamping portion (5). Each jaw (4, 5) is mounted on a clamp arm (6a, 6b) which arms (6a, 6b) are connected to one another by means of a clamp arm guide shaft (7). The distance between the jaws (4, 5) may be varied by means of an adjusting wheel (8) moveable along a threaded screw (9) which causes movement of the clamp arm (6) along the shaft (7). Clamp arms (6a, 6b) are spaced apart from one another by means of clamp assembly guide shafts (10). The distance between clamping means (2, 3) may be varied by movement of the clamp arm (6a) relative to clamp arm (6b) along the shaft (10). The jaws can be rotated. <IMAGE>
