The protective cap has a link member (43), which is connected with an axial outer end of the socket section (16). A flap (18) is connected with the socket section via the link member. The flap is forced into a passive closure position by the tensioned link member. In this position, the flap engages on an axial, outwardly facing edge zone (23) of the socket section. Securing devices (23,46) define an active closure position, in which the flap is manually movable and is secured releasably with the socket section. In the outwardly facing surface of the flap a concave cavity is formed. |
