Abstract:
1. A tube joint comprising: a body made of a resin material having a distal edge and an opening at a second end of said body; an attachment/detachment mechanism into which a tube is configured to be inserted and which comprises: a ring member fitted to an outer circumferential wall surface of said body at said second end, and wherein when a force is applied to the inserted tube to pull out the tube from the attachment/detachment mechanism, said attachment/detachment mechanism is constructed such that said fastening section is displaced together with said collet along an inner circumferential surface of said engaging member in a direction opposite to an inserting direction of the tube and that said engaging member engages with said taper section of said collet to press said fastening section radially inwardly toward the outer circumferential surface of the tube, and where when the force is applied to the inserted tube to pull out the tube from the attachment/detachment mechanism, said seal member is displaced together with the tube in the direction opposite to the inserting direction of the tube, and said seal member abuts against said fastening section and said collet for preventing the tube being disengaged from said attachment/detachment mechanism.
