Tubular connection with self-locking threading used in the oil industry

A threaded connection comprising:

• a first and a second tubular component, each including a respective male and female end,
• the male end comprising, on its external peripheral surface, at least one threaded zone and finishing in a terminal surface which is orientated radially with respect to an axis of the threaded connection, the female end comprising, on its internal peripheral surface, at least one threaded zone and finishing in a terminal surface which is orientated radially with respect to the axis of the threaded connection,
• the male threaded zone comprising a first portion in which a width of teeth, CWTp, increases from a value CWTpmin corresponding to a width of a tooth which is closest to the terminal surface of the male end to a value CWTpmax corresponding to a width of a tooth which is furthest from the terminal surface, while a width of teeth CWTb of the female threaded zone decreases from a value CWTbmax corresponding to a width of a tooth which is furthest from the terminal surface of the female end to a value CWTbmin corresponding to a width of a tooth which is closest to the terminal surface, such that the threaded zones cooperate in accordance with a self-locking make-up, and:
