A threaded coupling device for pipes, with a metal sealing ring, whose clamping surface acts on the end faces of the sealing ring, beveled in a conical shape, causing a radial contraction of the ring on the surface of the pipe, characterized in that each of the parts of the threaded joint has at least one protruding annular edge above the sealing ring, formed by the intersection of two surfaces, and because the sealing ring has, at least at its two ends of the bore, grooves a In this manner, when the parts of the threaded joint are screwed in, the grooves penetrate radially, and to a small extent, into the surface of the tube, without the joint ring deforming substantially.
