The two gripper parts (5, 6) of a gripper are mounted so as to be pivotable on a shaft (12) which, in turn, is mounted rotatably in a holder (13). Connected to this shaft (12) so as to be fixed against rotation is closing lever which bears at its end a follower roller which interacts with fixed closing links. Furthermore, a resting part (16) for a compression spring (18) is connected to the shaft (12) via a spreader ring (17) so as to be fixed against rotation. This compression spring (18) is supported at its other end on a bearing part (5) which is integral with the one gripper part (5). A pivot movement of the closing lever results in a corresponding clockwise pivoting of the resting part (16), as a result of which pivoting of the one gripper part (5) into the clamping position is brought about via the compression spring (18). This one gripper part (5) is blocked in its clamping position in which the compression spring (18) is compressed and exerts a corresponding clamping force.
