<p>The spacer has bolts including a shaft (3c) with a U-shaped groove, a V-shaped groove and a sawtooth shaped groove, where grooves contiguously runs in a row over a total or a part of a longitudinal extension of the shaft. A bushing (3a) includes two slots (3d) lying parallel to each other in a plane. The slots traverse a wall (1) of the bushing so that parallel sides of an elastic retainer (6) engage in the bolts, which attach the grooves at the shaft of an axis in the bushing. The retainer is arranged in the slots.</p> |
