Abstract: A slip-on type pipe joint including a socket, a spigot and an annular rubber packing disposed on the inner periphery of the socket at an axially intermediate portion thereof and compressible by the outer periphery of the spigot against the inner periphery of the socket to seal the clearance between the socket and the spigot with its restoring force. The joint further comprises an engaging member detachably attached to the inner periphery of the socket at its open end and radially inwardly projecting from the periphery, a protrusion formed on the outer periphery of the spigot and positioned between the packing and the engaging member, and a split lock ring disposed between the protrusion and the engaging member and fitting around the spigot with a diametrically contractive force. The lock ring is engageable with the engaging member and with the protrusion to prevent the spigot from slipping off the socket.
