金具。[Scope of Claim for Utility Model Registration] A joint body having a plurality of cylindrical connection ports into which corrugated flexible metal tubes are inserted, and a joint body that is fitted onto the flexible metal tubes and screwed into each of the connection ports separately. a plurality of nut bodies, and a retaining ring that is set inside the connection port to which the nut bodies are screwed together; and is formed of a truncated cylindrical body with an inner peripheral diameter larger than the outer peripheral diameter of the metal flexible tube, and a tapered surface is formed on the outer periphery of the projecting part. , the nut body has a contact portion that pushes the retaining ring when screwed into the connecting port and allows the retaining ring to contract in diameter, and the connecting port is pushed back by the nut body. A tapered guide surface that slides on the tapered surface of the retaining ring to advance the retaining ring while reducing its diameter inward in the radial direction, and an overhanging portion of the retaining ring whose diameter has been reduced. A connecting fitting for a metal flexible tube relay, characterized in that it has an annular convex portion that abuts an end of the metal flexible tube that is engaged with and pressed against the metal flexible tube.
