It furthermore has a tightening device which has a compression spring, which acts in the direction of rotation, an intermediate ring acted on thereby which is rotatable with respect to the chuck body and the clamping sleeve, an unlockable locking member on the intermediate ring, and an outside, rotatable gripping sleeve having an inner stop for the intermediate ring.
