ABSTRACT:
A quick disconnect coupling element which includes a laterally ported female socket body having a hose-receiving neck projecting therefrom. A pair of spaced lugs are disposed on opposite sides of each of a pair of latching handle ports opening into the female socket body, and each lug pair functions to pivotally support a latching handle having a camming surface located inside the female socket body. A wire safety spring element is mounted adjacent each latching handle and prevents the handle from prematurely unlatching a male coupling element from the female socket body as a result of vibratory forces.
