<p>The socket part (1) has base body (2) with a channel (18) for a plug. At least one locking pin fits in at least one slit (36) on the base body. At least one slot (38) contains a holder body that projects out of the base body. A pressure ring (11) sits on the base body and co-operates with the end of the locking pin. At least one compression spring unit acts between the pressure ring and an abutment ring (9) to bias the locking pin against the base of the slit. An actuator sleeve (6) slides on the base body between three positions. At least one inclined surface extends between front (48) and rear (51) support faces. A valve (5) in the channel is held open when the plug is inserted. The front support face is spaced so that a holder body projects into the channel. The rear support face has a space so that the holder body does not project into the channel. The holder body is at the same height as the locking pin when it is next to the front support face. In the rest position of the actuator sleeve, the rear support face projects over the rear end of the slot and the inclined surface is spaced from the rear end of the slot, so that the holder body is held with little play at the height of the locking pin.</p> |
