ABSTRACT:
This invention relates to a connector of a quick connection allowing tight connection of a rigid tube provided, at some distance from its free end intended to be fitted in the inlet of the connector, with a bead projecting radially with respect to the outer surface of the tube and presenting a substantially radial side opposite said end. The connector presents a first inner housing comprising an O-ring capable of coming into contact with the outer surface of the tube between its free end and its bead and a second inner housing to receive a locking ring elastically deformable in the radial direction. The locking ring is formed by a thin metal band presenting a generally oblong profile, the central region of said ring being constituted by substantially cylindrical portions whose diameter in the free state is at the most equal to the diameter of the tube. The zone located at one end of the large diameter of the oblong profile is constituted by a bridge in the form of an upturned U whose base essentially forms a part radially projecting outside the body of the connector.
