Abstract: The invention relates to a clamping device which contains a structure (1), two carriers (2, 3) which are disposed in the structure (1) and have at least one clamping jaw (5, 6) each, and an adjusting spindle (4) for adjusting at least one carrier (2). In order to make possible a compact, relatively inexpensive construction which is protected against contamination, the carriers (2, 3) are constructed as half shells surrounding the adjusting spindle (4).

Abstract: A clamping device is described with a body, which has a substantially U-shaped cross-section, and at least one slide which can be shifted in the body by a screw spindle and which has at its upper side a plurality of fixing recesses arranged along the slide longitudinal direction with a mutual centre-to-centre spacing for selective engagement of a corresponding fixing projection of a jaw which can be repositioned and a plurality of threaded bores for fixing screws of the jaws. A plurality of cover sheets are provided on the upper side of the slide and they are slidably guided on the slide in its longitudinal direction and have a length which corresponds to the centre-to-centre spacing (pitch) of adjacent fixing recesses. The number of cover sheets corresponds to the number or centre-to-centre spacings (t) and the cover sheets can slide over the region of the currently unused fixing recesses and threaded bores.
