Claims

[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. and a retaining ring set inside the connection port to which the nut bodies are screwed, and the retaining ring has an inner circumferential diameter larger than an outer circumferential diameter of the flexible metal tube. The nut body has a large oval shape, and its cross-sectional shape is circular, elliptical, or a similar polygonal shape, and the nut body supports the retaining ring when screwed into the connection port, and also supports its removal. The connection port has a contact portion that allows the retaining ring to contract in diameter, and the connecting port has a taper that slides on the retaining ring pushed by the nut body and moves the retaining ring forward while contracting the retaining ring radially inward. A metal flexible tube relay comprising: a shaped guide surface; and an annular convex portion that engages with a diameter-reduced retaining ring and abuts against the end of the flexible metallic tube that is pressed by the retaining ring.
