A fastening pawl (40) provided at one end of the cylindrical joint body (14) is pressed radially inward by the inner wall surface of a nut (20) for engaging with a diametrally expanded outer surface (16a) of the tube (16). An annular projection (60) at the end surface of the nut is screwed to the joint body to regulate the screwing amount of the nut on the joint body. |
