ABSTRACT:
A coupling for sealingly connecting an end portion of a hose to a nipple at one end of a pipe has a sleeve with a first section which surrounds the nipple and a separately produced second section which is form-lockingly connected with the first section and is received in the end portion of the hose when the coupling is assembled. The first section has a washer-like portion which is integral with axially extending prongs engaging a single ring-shaped protuberance or discrete tooth-shaped protuberances at the exterior of the nipple. The second section of the sleeve has an internal groove for a sealing ring which engages the external surface of the nipple. A tubular clamping member is shrunk onto the end portion of the hose and surrounds the second section of the sleeve.
