Abstract: Disclosed is a self tightening hose coupling which when applied to a hose comprises a floating sandwich like structure including a floating stem, hose, and tapered wedge segments which operate as a unit and float between a nipple and a compression sleeve. The compression sleeve has a tapered interior which matches the taper of the wedges and is constructed to permit the interior placement of a locking ring which operates against a split retaining ring mounted on the nipple thereby preventing the floating sandwich like structure from being pulled out when internal fluid or tensile pressures, occur under operating conditions.
