  • the stopping device 23 is in the figures provided as a wing at the tightening element 21 .
  • the wing which is shown in detail in FIG. 6 f , may be provided by bending or folding an area 31 of the tightening element 21 , wherein, subsequently, the bended or folded area is attached to the tightening element 21 through a plastic weld 32 or through another means of attachment, such as gluing, seam etc.
  • the wing 31 is engaged against the opening 26 in the channel 22 and prevents the tightening element 21 from sliding further back into the channel 22 .
  • FIG. 6 a An alternative stopping device 23 is shown in FIG. 6 a .
  • the stopping device 23 is provided using a stiffened area 33 .
