ABSTRACT:
A hose coupling according to the present invention for securing a hose has a cylindrical nipple and a cylindrical socket disposed radially outwardly thereof. A plurality of circumferentially extending annular hose gripping projections are provided on a radially inner surface of the socket in a predetermined interval along a longitudinal direction of the nipple. The hose comprises an elastic tube layer and a reinforcing layer disposed radially outwardly thereof, and is to be secured between the nipple and the socket by crimping the socket after the hose is inserted between the nipple and the socket. At least one hose gripping projection of the plurality of hose gripping projections protrudes radially inwardly of the socket greater than other hose gripping projections.
