<p>A coupling according to the present invention has a socket (2) and a plug (30) that is inserted into and connected to the socket. The socket includes a socket body (10) having a first through-hole (13b) for a plug-locking element (12b) and an elongated second through-hole (13a) for a sleeve-actuating element (50), and a sleeve (50) set around the socket body. The sleeve is urged by a spring member (15) toward a position for pressing the plug-locking element (12b) against a locking recess (34) of the plug to prevent the plug from slipping out of the socket. The sleeve has a locking surface (50b) that presses the plug-locking element in the position described above. When being inserted into the socket, the plug engages with the sleeve-actuating element to move the sleeve rearward, thereby disengaging the locking surface from the plug-locking element.</p> |
