PURPOSE:To provide an inexpensive tube joint by inexpensively constituting a tubular fastening member. CONSTITUTION:A tubular body part 100 is provided with an annular rib 110 projecting from the inner peripheral surface of an axial hole 101 extending from an axial one end opening 100a to the axial inside. When the end of a tube 1 is inserted into the axial hole 101 from the opening 100a, a claw part of a tubular fastening member 120 held farther inside than the annular rib 110 is deformed radially inward to bite into the outer peripheral surface of the tube 1 by a drawing-back operation in the opposite direction to the direction of inserting the tube 1. This fastening member 120 is provided with a cylindrical part, a plurality of arm parts extending parallel to the axis from the cylindrical part and the claw part extending through a bent part to the free end of the arm part in the centripetal direction and is formed integrally with a plate material. |
