JOINT, AND SOCKET AND PLUG USED FOR THE JOINT

Document Type and Number:

WIPO Patent Application WO/2008/062857

Kind Code:

A1

Abstract:

A joint comprises a socket (2) and a plug (30) inserted in 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 a second elongated through-hole (13a) for a sleeve operating element (12a), and a sleeve (50) displaced around the socket body. The sleeve is biased by a spring member (15) toward a position where the sleeve presses the plug locking element (12b) against the locking recess (34) of the plug to prevent the plug from being extracted. The sleeve has a locking surface (50b) for pressing the plug locking element at that position. When the plug is inserted into the socket, it is engaged with the sleeve operating element and the sleeve is moved backward so that the locking surface is removed from the plug locking element.
