ABSTRACT:
A coupling which serves to fluidtightly and separably connect the nipple at one end of a pipe with an end portion of a flexible hose has a sleeve with a first section which is insertable into the end portion of the hose and a second section form-lockingly or integrally connected with the first section and provided with axially parallel flexible prongs having openings for reception of discrete projections at the exterior of the nipple. A tubular clamping member is or can be integrally connected to and cooperates with the first section of the sleeve to sealingly engage the end portion of the hose. One or more sealing rings are inserted between the sleeve and the exterior of the nipple when the latter is received in the sleeve so that its projections enter or can enter the openings of the respective prongs.
