A connector comprising first and second interengagable connector elements, the first comprising a socket and the second comprising a spigot insertable into the socket of the first element, wherein the first element supports at least one radially displaceable locking member protruding into the socket and a displaceable collar for controlling the radial position of the or each locking member. The second element defines at least one groove extending from adjacent an end of the spigot and aligned to receive the or a respective locking member projecting into the socket. The collar is displaceable relative to the first element between a first position in which the or at least one locking member is caused to project at least a first distance into the socket and a second position in which the or at least one locking member is caused to project at least a second distance in the socket, the first distance being greater than the second. The or each groove has a first relatively shallow portion extending from adjacent the end of the spigot and a second relatively deep portion remote from the end of the spigot, the first relatively shallow groove portion being dimensioned to accommodate a locking member projecting the second but not the first distance into the socket, and the second relatively deep groove portion being dimensioned to accommodate a locking member projecting the first distance into the socket.
