ABSTRACT:
A nozzle is provided for the inflation or deflation of inflatable articles that are equipped with a valve stem having a flap valve, a cap, a hinge connecting the cap to the valve stem, and an annular depression on the external surface of the valve stem. The nozzle comprises an annular conduit equipped with a centrally disposed pin that protrudes partially from the conduit. The conduit is provided with a notch for accommodating the hinge on the valve stem, and a resilient ridge on the interior of the conduit for engaging the annular depression on the external surface of the valve stem, thereby securing the nozzle in place. In use, the nozzle is placed over the valve stem in such a way that the notch is disposed around the hinge. The pin engages the flap valve within the valve stem, thereby allowing the free flow of air through the nozzle.
