Abstract
A quick connector assembly for interconnecting of two conduits in fluid flow relationship is provided. The connector assembly has an elongated tubular housing connected to one conduit and adapted to receive a terminal end portion of another conduit in axially inserted relationship. A retainer cap rotatably attachable to an end of the housing includes a plurality of spring fingers that project axially inwardly of the housing and that engage with an annular ring formed on the axially inserted conduit to mechanically engage therewith and lock together the housing and conduit with a fluid seal provided between the housing and conduit. A visual and tactile indicating mechanism is included to provide a perceivable indication that the housing and conduit are mechanically interlocked. This indicating mechanism includes a spring biased indicator tab which is displaced radially outwardly through an aperture in the wall of the housing where it may be perceived, visually or tactilely, by the annular ring on the conduit when it is inserted into locked engagement. The retainer cap locks onto the housing by locking tabs carried on the housing and projectable through apertures in the cap to provid…
