  • the carrier part is thus designed as a single-layer basic matrix from which fastening straps of different sizes and shapes can be easily separated Locking parts along the distances that increase the inherent stability of the base matrix is facilitated. Furthermore, due to the existing distances, a clean dividing line between the carrier part and the respective fastening strap is achieved compared to solutions in which the fastening straps are separated from a base material without any gaps.
