The invention concerns a threaded connection comprising a first and a second tubular component, each being provided with a respective male (1) and female (2) end, the male end (1) comprising, on its external peripheral surface, at least one threaded zone (3) and finishing in a terminal surface (7) which is orientated radially with respect to the axis (10) of the connection, the female end (2) comprising, on its internal peripheral surface, at least one threaded zone (4) and finishing in a terminal surface (8) which is orientated radially with respect to the axis (10) of the connection, the male threaded zone (3) having a first portion in which the width of the teeth, CWTp, increases from a value CWTpmin corresponding to the width of the tooth which is closest to the terminal surface (7) of the male end (1) to a value CWTpmax corresponding to the width of the tooth which is furthest from said terminal surface (7), while the width of the teeth CWTb of the female threaded zone (4) decreases from a value CWTbmax corresponding to the width of the tooth which is furthest from the terminal surface (8) of the female end (2) to a value CWTbmin corresponding to the width of the tooth which is closest to said terminal surface (8), such that the threaded zones (3, 4) cooperate in accordance with self-locking make-up, characterized in that: CWTpmin/CWTbmax ≥ 0.2 and CWTbmin/CWTpmax ≤ CWTpmin/CWTbmax. |
