The top member 1 is provided on the inward sides of two oppositely disposed side walls thereof with guides 6 by which the top member can be clipped onto the axle 3 in a sequence of movements (Figs. 1 - 4). During clipping of the top member onto the axle, a projection 11 on the top member presses against and bends the axle.
