Abstract
A tubular joint adapted to connect a pair of pipes is formed by a joint body made of a synthetic resin having a pair of connection ports integrally formed on respective sides thereof. An engaging groove is formed around an axial line on an outside circumferential surface of each of the connection ports, and a synthetic resin-made fall-out preventing member is fixed at an end portion of each of the connection ports. An outside cylindrical portion of each of the fall-out preventing members has a tapered surface adapted to enable the fall-out preventing members to be press-fitted onto the respective connection ports, and includes a plurality of engaging portions that are engaged with the engaging groove formed around the axial line on the outside circumferential surface of each of the connection ports as the fall-out preventing members are press-fitted thereon. And an inside cylindrical portion of each of the fall-out preventing members extends toward a center of the connection ports in an inclined manner, and includes a plurality of fall-out stoppers whose tip ends are shaped so as to be engaged in a groove portion formed around an axial line on the outside circumferential surface of the respective pipes to be connected as the pipes are inserted and fitted in the connection ports.
