Tap or valve
First Claim
1. A tap comprising a first tube, a second tube and a sleeve of flexible elastic material placed over abutting or nearly abutting ends of the tubes to form a flexible elastic coupling between said tubes to allow fluid passage between said tubes when said tubes are substantially coaxially aligned and to allow displacement of one of said tubes substantially at right angles to the other by stretching said sleeve across an open end of one of said tubes to close said fluid passage, the facing ends of the tubes each comprising at least one flange so that when the tubes are displaced to the closed position at substantially right angles to one another, the flanges engage to help to maintain the displaced tubes in the closed position.
