A split, annular hose clamp for clamping one end of a length of thin wall, high pressure, fire hose on the nipple, or insert, of a hose coupling has relatively blunt, alternate ribs and grooves opposite to, fitting and mating with similar ribs and grooves on the nipple and has a pair of machine screws each extending across the butt joint of a pair of one-piece, substantially idential halves in which the heads are within the confines of the head recesses so that there are no sharp protuberances to cut fire hose. The screw heads are socketed for turning and the clamp is of less diameter than the coupling.
