ABSTRACT:
A coupling which serves to connect the nipple of a pipe to the end portion of a hose has a sleeve with a tubular section insertable into the end portion of the hose and one or more flexible prongs which extend from one axial end of the tubular section and can be bent into engagement with an external retainer of the nipple. The prongs are made of a ductile metallic material. A sealing ring is inserted between the exterior of the nipple and the interior of the tubular section, and a tubular clamping member is used to urge the end portion of the hose against the external surface of the tubular section of the sleeve. The prongs are spread apart during introduction of the nipple into the sleeve, and are thereupon flexed inwardly to engage the retainer.
