ABSTRACT:
A quick-release plug-in coupling device includes a female member to be connected to one hose and including a body, a valve seat internally of the body, and at least one opening through the body. A male member to be connected to another hose includes a body sealingly fittable into the body of the female member, the male member body having formed therein at least one recess. A valve member is positioned within the female member for movement between closed and opened positions relative to the valve seat. At least one actuating member is positioned outwardly of the female member and has an integrally formed elastic member extending inwardly through the opening in the body of the female member. The elastic member has an inner end fittable into the recess in the body of the male member. The actuating member is selectively manually movable axially of the female member between locking and release positions. The actuating member is constructed to prevent the actuating member from being separated from the female member when the actuating member is in the release position and also for preventing unintentional axial displacement of the actuating member relative to the female member when the actuating member is in the locking position.
