ABSTRACT:
A female hose coupling comprises a rigid sleeve for receiving a conduit stub on a liquid tank. The female hose coupling includes a smaller diameter conduit which slips inside a flexible hose. A pair of pivoted levers are mounted on the exterior of the rigid sleeve. A cam on each of the levers extends through an opening in the sleeve to engage a shoulder on the conduit stub. A protective sleeve surrounds the end of the female hose coupling and remains in place during normal use of the flexible hose. The protector provides a passage to accommodate the pivoted elvers and allow the coupling to operate in a normal fashion.
