FIELD: technological processes.
SUBSTANCE: invention relates to devices for connection of hoses to metal carcass with non-detachable end fittings. Device includes rubber-reinforced hose with remote rubber layer at the end. On inner surface of coupling on hose end side there is annular shaped projection, and the external surface of the nipple is equipped with an annular shaped protrusion located beyond the projection of the coupling so that after deformation there formed is a deformed zone of the high pressure hose, which prevents the nipple output from the hose.
EFFECT: invention provides reliable connection of sleeve with simultaneous simplification of manufacture of coupling and nipple.
