Abstract
A pipe coupling is disclosed which comprises a plug () and a socket (). When the plug is inserted into the socket, the plug first urges sleeve actuators () radially outward to axially move a sleeve () and, thereafter, urges locking elements () radially outward to move the sleeve further. Eventually, the locking elements and sleeve actuators are fitted within a locking recess (-) of the plug to securely connect the plug and the socket.
