The closing part has rest units (8, 9) including flexible tongues that are arranged parallel to each other. The tongues include barbed hook-like head strips, which form an end of long sides of the closing part and are arranged on a lower surface of the closing part. The strips are engaged behind an undercut (6) of a groove (5) at horizontal and vertical cross-beams (3, 4), respectively. |
