<p>PROBLEM TO BE SOLVED: To facilitate the connection of resin pipes with each other. SOLUTION: A main barrel body 2 having connecting holes 3 at both the sides of a resin pipe 1, is divided and formed into a plug body 4 to be mounted to one pipe, and a socket body 5 to be connected with the other pipe. One side of the plug body 4 is formed into a cone part 6 having a tapered surface in a tapered shape, and one side of the socket body 5 is formed into a tapered hole part 9 having a tapered surface in a tapered shape to be engaged with the cone part 6. An annular 7 is formed in the outer circumferential surface groove of the cone part 6, and concurrently, one-split lock ring 8 capable of being widened/contracted is mounted to the annular groove 7, and an annular engaging groove 10 to be engaged with the lock-ring 8 is formed up in the inner circumferential surface of the tapered hole part 9.</p> |
