FIELD: machine building.
SUBSTANCE: device includes a rubber-reinforced hose with a remote inner rubber layer on the end, the inner surface of the coupling is conical, and the outer surface of the nipple is equipped with a conical surface made opposite the coupling cone, so that conditional vertices look to sleeve end, which when squeezed create zone of increased pressure, which ensures reliable connection and simplifies manufacturing of coupling and nipple.
EFFECT: invention relates to devices for connection of sleeves with metal frame with permanent end fittings and can be used in transport, automotive, oil and other industries.
