A washer (8) is provided between the two locking parts (6, 9) and contains a space in the side facing the first locking part, the space having a shape corresponding to that of the first locking part. The holder contains a mounting opening (5) and an anchor part (1) with a head (2) and shaft (3), the head protruding from the shaft axis at a first angle by a first radial distance which is less than the projection of the opening at this angle, and protruding from the shaft axis at a second angle by a second radial distance which is more than the projection of the opening at this angle. A first elastic locking part with at least one protruding section (7) and a hole is provided, the size of the hole being adapted to receive the anchor part shaft. The protruding section is located at a distance from the centre of the hole which is at least equal to the smaller projection of the anchor part head. A second locking part is used to fix the first locking part into position so that the protruding section is located on the side of anchor part head closest to the anchor part shaft axis. |
