A vehicle seat belt retractor with a belt shaft (10) and a coupled profile head lockable to a housing. A force-limiting device has at least two elements (11, 12) between profile head and belt shaft (10). Free ends (15, 16) of the force-limiting elements (11, 12) are coupled to each other by a connecting tube (13) via a coupling element (18). The coupling element (18) has a hook-shaped spring element with a locking hook (19) which slides over the connecting tube (13) when the belt shaft (10) rotates and engages in a locking groove (20) to couple the connecting tube (13) to the belt shaft (10). At a preset angle of rotation of the belt shaft (10) is reached, the bridging device releases the coupling element (18) for the locking hook (19) to latch into the connecting tube locking groove (20).
