Abstract: A tubular coupling is provided. The tubular coupling has a female endpiece with an axial orifice into which a male endpiece provided with a collar is designed to be inserted axially. The female endpiece includes a latching locking member that is designed to be deformed elastically in a radial direction by mechanical interference during insertion of the male endpiece into the orifice and to become locked against the back of the collar. The coupling further includes a ring mounted to slide coaxially with the orifice around the female endpiece and that forms a ramp that is oblique relative to the axial direction in order to deform the locking member elastically in a radial direction by the lever effect when the ring is subjected to axial traction in the direction for inserting the male endpiece into the female endpiece so as to release the male endpiece from the female endpiece.
