The cross section locked between the pressing surface is U-shaped toward the connecting flexible tube side, and the inner diameter of both ends of the U-shape is larger than the outer diameter of the tube and one end in the circumferential direction is cut out so that the diameter can be reduced. and a retainer having a stopper in the metal member whose inner diameter is smaller than the outer diameter of the tube and which can be expanded and contracted, and when the retainer is locked by screwing a nut onto the main body. By inserting the flexible tube from the rear end of the nut, the stopper inside the retainer expands in diameter and the tube end comes into contact with the abutting surface of the main body.After this, by tightening the nut, the retainer moves to the parallel inner surface of the main body. A joint for a flexible pipe, characterized in that the metal member is moved and reduced in diameter, and both ends of the inner diameter side of the metal member engage with the waveform of the flexible pipe to press the waveform part of the tip of the flexible pipe to the abutment surface of the pipe end of the main body.
