ABSTRACT:
A quick connector for forming a joint in a fluid line consists of a female connector body having a bore which receives a male member. A sleeve surrounds and is secured on the male member in close fitting relation with the male member and with the female connector body. A retainer extends between the sleeve and a radial face formed in the connector body to secure the male member in the connector body. A secondary retainer provides enhanced retention capability. An optional plug may be positioned in the bore entrance to prevent introduction of external contaminants.
