Abstract
A coupling according to the present invention has a socket () and a plug () that is inserted into and connected to the socket. The socket includes a socket body () having a first through-hole () for a plug-locking element () and an elongated second through-hole () for a sleeve-actuating element (), and a sleeve () set around the socket body. The sleeve is urged by a spring member () toward a position for pressing the plug-locking element () against a locking recess () of the plug to prevent the plug from slipping out of the socket. The sleeve has a locking surface () 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.
