<p>The part (8) and its support have male (3) and female (9) means of interconnection. The male means (3) consists of a T part whose vertical bar (4) is coaxial with the axis of rotation (Z-Z') and whose cross bar (5) is oriented towards the female means (9). The female means (9) consists of a receiving member with a slot (11) shaped so as to allow the cross bar (5) of the T to enter said receiving member. Said slot (11) gives entrance into a cavity (12,13) which is at least in portions of a cylinder and in which there is at least one obstruction (16,17) which restricts the rotation possible to said cross bar (5) in said cavity (12,13). <IMAGE></p> |
