摘要： A threaded connection includes first and second tubular components, each including a respective male and female end. The male and female ends each include at least one threaded zone and finish in a terminal surface. The male threaded zone includes a first portion in which a width of teeth, CWTp, increases from a value CWTpmin corresponding to a width of a tooth closest to the terminal surface of the male end to a value CWTpmax corresponding to a width of a tooth furthest from the terminal surface. A width of teeth CWTb of the female threaded zone decreases from a value CWTbmax corresponding to a width of a tooth furthest from the terminal surface of the female end to a value CWTbmin corresponding to a width of a tooth closest to the terminal surface. The threaded zones cooperate in accordance with a self-locking make-up, with CWTpmin/CWTbmax≥0.2 and CWTbmin/CWTpmax≤CWTpmin/CWTbmax.

According to the invention, the male tubular element (EM) initially comprises a local annular added thickness (SA1) at a fourth inner surface (SI4) which projects out from the second abutting surface (SB2). The third inner surface (SI3) of the female tubular element (EF) comprises an annular groove (G1) which, after screwing, is placed at the first outer surface (SE1) and the annular added thickness (SA1). The male and female elements are shaped such that, after screwing, the first lip (L1) is housed in the annular housing (LO) and the second and third abutting surfaces rest against one another, in order to enable the formation of an annular shoulder (EP) at the first outer surface (SE1) during diametral expansion in the plastic deformation region, said shoulder having the shape of part of the groove (G1) and being in hermetic clamping contact therewith.
