ABSTRACT OF THE DISCLOSURE A pipe joint for preventing separation comprising a holding member connectable to an annular outer flange formed at the end of a socket and surrounding the outer periphery of a spigot outside the socket, the holding member being annular or being adapted to form an annular shape, the holding member being provided on its inner periphery with a tapered surface increasing in diameter toward the socket; a stopper in the form of a ring divided at one portion and provided with an outer peripheral tapered surface increasing in diameter toward the socket and with engaging edges in circumferential rows on its inner periphery, the stopper being interposed between the tapered surface of the holding member and the spigot outer periphery; and tap bolts extending through the holding member at suitable portions along its circumference for pressing the stopper from outside against the spigot outer periphery. Because the stopper is thus shaped, the joint is easy to assemble and manufacture. When the spigot acts to slip off with the tap bolts tightened up, a diametrically constricting force acts on the spigot uniformly circumfer- entially thereof without eny unevenness to reliably prevent separation of the spigot from the socket.
