装置の離脱防止継手。 A joint for connecting a laying pipe to a pulling device that is connected to a pilot pipe buried in the ground and pulled out in the axial direction of the pilot pipe, and has a stopper projecting in the radial direction along the outer periphery. It has a socket part into which a pipe socket can be inserted and has an annular groove formed on the inner periphery of the opening end, and a divided piece that is accommodated in the annular groove and divided into a plurality of pieces along the circumferential direction. and a stopper ring formed in an annular shape and having a spring that connects each end of the divided piece, the stopper ring being configured to be biased to expand its diameter by the spring, and further comprising: screwed into the annular groove from the outer peripheral surface of the stopper ring in the radial direction of the socket part, presses the outer peripheral surface of the stopper ring to reduce the diameter of the stopper ring, and presses the stopper ring against the outer surface of the insertion port of the installation pipe. A pipe drawing device comprising a plurality of set bolts in a circumferential direction that enable the stopper ring to lock with the stopper when an extraction force is applied between the socket and the insertion port. Separation prevention fitting.
