ABSTRACT:
A hose coupling employs a tailpiece, a sleeve and collar to prevent the hose to be removed from the coupling. The tailpiece includes an exterior having: a first sinusoidally shaped (in cross-section), partially diamond shaped knurled contour, and, a cylindrically shaped interior. The sleeve includes an interior second sinusoidally shaped contour reciprocal to the first undulating contour of the tailpiece. The sleeve includes first and second halves each having two sets of fingers which interengage the fingers of the other half. A hose is disposed between the sleeve and the tailpiece and the hose includes a grounding wire which engages the collar or the sleeve. The collar includes first and second halves and each of the halves of the collar interengage the sleeve urging the sleeve against the hose compressing the hose against the contour of the tail piece.
