ABSTRACT:
A hose coupling wherein one terminal portion of the hose surrounds a first circumferentially extending external rib of a nipple. The rib is adjacent to the free end of the nipple and is separated from a second external rib by a cylindrical portion of the nipple. The terminal portion of the hose is surrounded by an annular clamping member which has a circumferentially complete annular portion surrounding the hose and being spaced apart from the nipple as well as several axially parallel elastic prongs which surround the first rib and the cylindrical portion of the nipple and have inwardly extending projections engaging that flank of the second rib which faces away from the first rib. Certain prongs are further provided with teeth which abut against the end face of the terminal portion of the hose. A split ring is received in a composite groove which is provided in the external surfaces of the prongs to bias the prongs against the terminal portion of the hose so that the terminal portion sealingly engages the cylindrical portion of the nipple. The end portions of the split ring are provided with claws which are in engagement with but are separable from each other.
