A sleeve-type pipe joint 10 has a joint body 11 having a cylindrical projection 12 adapted to be inserted into a pipe 40 to be connected; a ring member 20 having a larger inner diameter than an outer diameter of the pipe 40; and a resiliently deformable, cylindrical sleeve member 30 moved into a space between the ring member 20 and the pipe 40, at least one of an inner surface of the ring member 20 and an outer surface of the sleeve member 30 being provided with a tapered portion, such that when the sleeve member 30 is moved into the ring member 20, the sleeve member 30 is deformed inward, resulting in tight connection of the inner surface of the pipe 40 to the outer surface of the cylindrical projection 12. When the ring member 20, the sleeve member 30, and the joint body 11 are assembled, the ring member 20 and the sleeve member 30 resist detachment from the assembled pipe joint 10.
