CONSTITUTION: A female element has a cylindrical recessed part 12 corresponding to a guide surface and a sliding part, or fitted to a guide surface 11 and a plastic insert piece 3 to an insert part 10 thereof, and the insert part 10 is connected to a substantially U-shaped anchor member 13. The plastic insert piece 3 has a frictional member 14 for enclosing the sliding part 7 of a male element, and is fixed by a screw 4 crossing the U-shaped anchor member 13 and a fixing member 15 of the insert piece, and this screw has an additional function. When the bottom part is seen from the top, the screw 4 has a head 16 in which a groove 17 is deformed, and the length of the head is suited to the mounting or the mounting to a scheduled position.</p> |
