ABSTRACT:
A female assembly of a quick connect/disconnect coupling including an annular locking/unlocking member molded in a thin wall construction of plastic material such that the annular member is capable of resilient flexure such that a manual movement applied to a pair of diametrically opposed unlocking portions in a direction to move the same radially together has the effect of moving a pair of diametrically opposed locking portions displaced 90.degree. from the unlocking portions radially outwardly. The locking/unlocking member is separate from and is mounted on an annular structure axially inwardly of an open end of the female assembly with the locking portions extending normally in a position to lock a tubular male member in an operative position therein or to unlock the same. The locking/unlocking member is movable from its normal locking/unlocking position to a positive locking position when opposing forces are applied tending to move the coupling apart.
