Abstract
A coupling which establishes a separable fluid tight connection between a nipple at one end of a pipe and one end portion of a flexible elastic hose has a sleeve with a tubular section insertable into the end portion of a hose and a set of elastic prongs which can engage a retainer at the exterior of the nipple when the latter is inserted into the sleeve. A tubular clamping member surrounds the end portion of the hose and biases it into sealing engagement with the tubular section of the sleeve. A sealing ring in an internal groove of the tubular section is in sealing engagement with the external surface of the nipple. The groove is formed by providing the tubular section with a radially outwardly extending corrugation which contributes to retention of the end portion of the hose between the tubular section and the clamping member.
