摘要：
The invention concerns a tubular joint wherein the radial expansion caused by the passage of an expander, inclined shoulder fittings (41, 43) formed respectively on a peripheral surface (8) of the female element (2) facing radially inwards and on a peripheral surface (7) of the male element (1) facing radially outwards are subjected to a relative axial displacement towards each other to be urged into sealed mutual contact with radial interference. The invention is useful in hydrocarbon wells.
