Abstract: A nut or a pair of nuts connecting the inlet fitting or a pair of inlet fittings of a water-dispensing fixture to respective connecting fittings is axially aligned with a collar threaded onto each connecting fitting and bearing upon a wall from which the connecting fitting emerges. An apron is axially shiftable on the cylindrical surfaces of the nut and collar which are axially aligned and of the same diameter to completely cover the nut or nuts. The apron is held in place by an elastic member seated in the collar.
