。 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 collar-shaped protrusion formed in the direction of the outer circumference of the tip. a socket into which the insertion port of the installation pipe can be inserted, and a groove in the circumferential direction formed on the inner periphery of the opening end; and a detachment prevention ring made of an elastic material disposed in the groove; The detachment prevention ring has a tongue piece formed on its inner surface so as to protrude toward the back from the open end side of the socket and to incline radially inward toward the back of the socket. When the socket is inserted into the socket, the tongue portion is pushed radially outward by a protrusion of the socket, and the tongue portion is pushed toward the back of the socket. 2. A detachment prevention joint characterized in that the detachment prevention joint is configured to be able to hold the laying pipe by engaging with the protruding portion in a direction in which the laying pipe is pulled out after passing through the protruding portion.
