1. A quick connector for making a verifiable connection with a tube, the quick connector comprising:
a receptacle having a tubular connector housing including a socket portion on one end of the receptacle, the socket portion including a pair of opening portions extending from an interior to an exterior of the socket portion and a pair of channels extending into the socket portion from a pair of wall members located on the exterior of the connector housing perpendicular to the opening portions;
a verifier having a pair of resilient legs extending from a base portion of the verifier, each resilient leg including a releasing member having an inwardly directed finger extending from each resilient leg, the finger including a front face having a sloped surface and a wedge shaped protrusion with a shoulder surface defining a top surface of the wedge shaped protrusion extending outward from each resilient leg, wherein each resilient leg extends through a respective channel into the interior of the socket portion with each releasing member top surface engaging an interior surface of each wall member that prevents the extraction of the verifier from the connector housing;
a retainer having inwardly directed engagement claws connected by spring bridging portions to a pair of outwardly projecting buttons, each button configured to be held in a mating fit within a respective opening portion in a preloaded position; and
an upset formed on an exterior surface of an insertion end of the tube, the insertion end and upset adapted to be installed into the socket portion of the connector housing and to lock the tube to the connector housing by a snap-engagement of the engagement claws with the upset and to deform each resilient leg to move and position each releasing member in alignment with the respective channel of each resilient leg allowing extraction of the verifier from the connector housing verifying the connection with the tube.
