The end pre-load tensioning device includes a seat belt retractor that takes up the end of the seat belt and a tensioning device connected thereto for the belt shaft of the seat belt retractor. The belt shaft is formed as a hollow shaft, and a blocking element blocks the belt shaft that is released in the event of an accident.
