ABSTRACT:
A tube joint includes a body into which a tube is inserted, a guide member which is arranged in the body, a chuck which engages with the outer circumferential surface of the tube to retain the tube, fastening pawls which protrude while being inclined by predetermined angles toward the inner circumference facing the tube on the chuck, a release bush which releases the tube from a fastened state, and a packing which is installed in the body. The packing surrounds the outer circumferential surface of the tube, and is displaceable in the axial direction of the body when a pressure fluid is supplied.
