A tubular threaded joint (30) comprising a first body (C1) ended by an outer stop (BE), and linked to a male thread (PC1) extended by an end portion (PT1) forming an inner stop surface (B1) at the axial end thereof, such that the joint comprises a second body (C2) defining, at a free end, a bearing surface (SA) for the outer stop, and having, on the inner surface thereof, an initial portion (PT2) linking the bearing surface to a female thread (PC2), screwed onto the male thread, and ending with a internal shoulder (El) facing the inner stop, such that the connecting profile between one of the outer stop, the inner stop, the bearing surface and/or the internal shoulder, has a profile whereof the diameter has a variable transverse cross-section along a length of the body that is less than one of the end portion or initial portion. |
