Abstract: An improved quick connector is provided. The quick connector includes a connector body, a connector head, a verification tab, and a locking clip. The connector body can be coupled to the connector head at multiple rotational orientations, and the connector head includes a retainer ring integrally formed therein. The connector head further includes an axial slot for the verification tab and includes first and second tangential slots for the locking clip. Upon insertion of a male fitting in the connector head, the verification tab is slideably displaced from a concealed position to a visible position, and the locking clip prevents retraction of the male fitting from the connector head.

Abstract: A female nozzle of a connection comprising a tubular main body defining a main axis of insertion and having a connection end adapted to receive a male nozzle, one retaining ring inserted into the main body on the connection end side, one internal annular recess having a bottom, a first and a second side wall, with the bottom and the first wall being defined by an internal shoulder of the main body and the second wall being defined by a circular section of the retaining ring, and with the annular recess not being contained in a transversal plane, which is perpendicular to the main axis of insertion and a sealing gasket being positioned in the annular recess. The first and second side walls are oriented toward the bottom of the annular recess, so that the latter has a trapezoidal section so configured as to clamp and hold the sealing gasket.
