A B S T R A C T A separation preventive pipe joint comprises a socket and a spigot inserted into the socket with an annular packing interposed therebetween. An annular gland connected to the socket has an axial packing presser projection and is internally provided with an annular receptacle groove. Arcuate engaging segments are incliningly disposed in a circular arrangement within the receptacle groove and retained there by elastic distancing members. The engaging segments are radially inwardly pressed by pressing bolts to engage in the spigot outer periphery. Each engaging segment elastically deforms in a manner of a Belleville spring in response to separating movement of the spigot to assume a posture generally perpendicular to the spigot outer periphery so that the engaging element engages in the spigot outer periphery more firmly.
