The band element having a head piece 4 which carries within a passage aperture 5 a resilient locking element which interacts with the profiled portion of the band element. The apparatus includes a spring-loaded band gripper 7 which is rotatable around a fulcrum 8. The gripper 7 is arranged on a spring-loaded sliding carriage 9 inside a housing 10. Moreover, there is provided a cutting lever 11 that is rotatable around a housing-fixed fulcrum 12 and carrying a knife 13 in the area of the band gripper. A trigger lever 14 is rotatable around a housing-fixed fulcrum 15. By means of the trigger lever, the sliding carriage 9 and the cutting lever 11 can be activated. The trigger lever 14 supports itself via a rotatable in sliding carriage 9. Thus, the cutting lever 11 is activatable via the rotatable curve element 16 and is actuated to cut the band only after release of the tensioning forces on the band.
