特徴とする金属可撓管用の継手。[Scope of Claim for Utility Model Registration] A cylindrical joint body into which a corrugated flexible metal tube is inserted, a nut body which is screwed into the joint body while being fitted onto the flexible metal tube, and the nut body is screwed together. and a retaining ring set inside the joint body, the retaining ring having an inner circumferential diameter larger than the outer circumferential diameter of the metal flexible tube, and a cross-sectional shape thereof. The nut body has a circular or similar polygonal shape, and the nut body has a contact portion that pushes the retaining ring when screwed into the joint body and allows the retaining ring to contract in diameter, and the nut body has a contact portion that allows the retaining ring to contract in diameter. has a tapered guide surface that slides on the retaining ring pushed by the nut body and advances the retaining ring while reducing its diameter radially inward, and a tapered guide surface that engages with the contracted retaining ring and moves the retaining ring forward. A joint for a flexible metal tube, characterized in that it has an annular convex portion that comes into contact with an end of the flexible metal tube that is pressed by a retaining ring.
