ABSTRACT:
A tubular joint including at least a pair of connection ports having an inner diameter substantially equivalent to an outer diameter of tubes to be connected, and a tubular connection part connecting the connection ports to each other. The connection ports each have a sealing member formed integrally thereon by extruding elastomer resin into a first recess formed around an axial line on an inner circumferential face of the connection ports, and the connection ports each have a fall-out preventing member coupled to an end part of the connection ports. The fall-out preventing member includes a ring-like member having an outer diameter sized for insertion into the connection ports, and a number of claws having leading edges located in a second recess formed around the axial line on the inner circumferential face of the connection ports and extending toward a center of the connection ports. When a tube is inserted into one of the connection ports, the claws slidably contact an outer circumferential face of the tube and are elastically deformed in a diameter-swelling direction to thereby enable insertion of the tube, whereupon the claws are brought into contact with the outer circumferential face of the tube due to an elasticity return pressure to thereby prevent the inserted tube from falling out of the one of the connection ports. At the same time, the sealing member is simultaneously brought into contact with the outer circumferential face of the inserted tube to thereby achieve an airtight coupling between the inserted tube and the one of the connection ports.
