Abstract: A belt retractor for a motor vehicle seat belt, with a belt shaft (1) in a housing frame, a profile head (2) which can be locked and a force limitation device (3) with a first end (4) coupled to the profile head (2) and a second end (5) is coupled to the belt shaft (1) and which allows a force-limited relative rotation of the belt shaft (1) with regard to the locked profile head (2). A connection tube (6) surrounds the force limitation device (3) with a locking hook (7), which during the relative rotation with regard to the profile head (2) slides over an external circumference of the connection tube (6) and on reaching a predetermined angle of rotation of the belt shaft (1) engages in a locking groove (8) on the connection tube (6), the coupling the connection tube (6) to the belt shaft (1) The connection tube (6) is produced in one piece with the profile head (2), so that on engagement of the locking hook (7) in the locking groove (8) the belt shaft (1) is locked via the profile head (2) to the housing frame in a non-rotational manner.
