Claims

[Claims for Utility Model Registration] A cylindrical joint body having a plurality of connection ports into which corrugated flexible metal pipes are inserted, and a joint body that is fitted onto the flexible metal pipes and screwed into each of the connection ports separately. a plurality of nut bodies, and a retaining member set inside a connection port to which the nut bodies are screwed together; The retaining member is formed of an elastic member having an inner circumferential diameter larger than the outer circumferential diameter of the crest of the flexible metal tube and is inserted into the connection port. It has a compressively deformable annular sealing material disposed in an annular space between the outer wall of the connection port and an engaging body provided at a plurality of locations in the circumferential direction of the axially outer end of the sealing material, When the nut body is screwed into the connection port, it pushes against the retaining member, and due to the push, the engaging body of the retaining member is moved forward and radially inward, and the end of the flexible metal tube is moved. After engaging, the end of the metal flexible tube is moved to follow the engaging body and pressed against the abutting part of the connection port;
It is characterized by having a tapered guide surface for compressing and deforming the sealing material of the retaining member by pushing the retaining member and bringing it into close contact with the outer surface of the flexible metal tube and the inner surface of the connection port. Connection fittings for metal flexible pipe relays.
