Abstract
A tube coupling including a female connector a body into which a male connector having an annular collar is inserted axially, and a connection element is provided. The connection element extends in a transverse direction within the body of the female connector. The connection element is designed to interfere mechanically with the collar during insertion of the male connector and to move transversely of its own accord towards the inside of the female connector. The connection element includes a locking hook that co-operates with a locking catch provided in the female connector. The hook goes past the catch as a result of the mechanical interference of the collar that drives axial and radial elastic deformation of the connection element. The hook locks against the catch when the connection element is fully pushed into the female connector.
