<p>A main body (1) of the pipe joint has a tapered inner surface (10) reducing in diameter toward a hose insertion port and a deformable collet (2), accommodated in the main body, is movable in its axial direction, and has an outward protrusion (22) engageable with the tapered surface (10). An engaging protrusion (23) is provided on the outer surface of the collet and an inward protrusion (11) is provided on the main body. When a hose (H) is inserted in the collet (2) and fluid pressure acts via the hose on the pipe joint, the collet (2) moves toward the hose insertion port and due to contraction of the collet the hose is securely grasped and reliably connected to the joint. If excessive fluid pressure acts thereon such that the outward protrusion (22) is moved into contact with the smallest diameter part of the tapered surface, the engaging protrusion (23) comes to abut the inward protrusion (11) and is arrested thereby so that the collet and the hose are prevented from slipping out of the pipe joint. <IMAGE></p> |
