Abstract

The spanner has a ratchet head (10) with receiving chamber (11) with receiving recess (12) on one side. The toothed rim (20) fits in the receiving chamber and the locking pawl (30) fits in the recess. A ring (40) has undulating sections (41, 42) and engages in the ring groove (23) of the toothed rim (20) so that the peak sections project into the hollow space (21) of the rim and the workpiece is clamped by the ring and cannot fall out. A cover can be inserted in to the underneath of the receiving chamber and locked in same by a ring.
