  • the positive-locking region which is preferably arranged at a first end of the tensioning band, can be connected in a form-fitting manner to an end plate. Thus, only more tension needs to be applied to the second end prior to joining the two ends. Thereafter, the two ends can be permanently or non-detachably connected to each other, for example, by welding and / or crimping or by a positive connection.
