The wall includes a first aperture for the clamping member and a second aperture comprising a first portion and a second portion. The first portion has a rim forming a bearing surface for the screw head. The second portion provides a free passage for the screw head. The axial passage can receive one end of the connecting member and the screw head, whereby (a) the screw head can be freely inserted into the axial passage of the fastening member and (b) the end of the connecting member and the screw head are immobilized by actuating the clamping member.
