The clamping device includes a body with two slides which can slide therein. The slides each carry a jaw that can be shifted opposite to the other jaw by an axially movable screw spindle. A central jaw can be fixed in the central region of the body. An abutment part is arranged at an operating end of the body, in the lower region of the slide and of the body facing away from the jaw. The abutment part has a lug which can shift to a limited extent in an end recess of the base part of the body. A spring arrangement is supported at one end on the lug and at the other end in a pocket of the base part. The abutment part includes a finger which engages in a longitudinal groove provided at the underside of the slide and carries a clamping element at its free end facing towards the central jaw, with which device the finger can be jammed in the longitudinal groove.
