FIELD: machine building.
SUBSTANCE: invention relates to devices for connection of sleeves to metal carcass with non-detachable end fittings. Device includes rubber-reinforced sleeve, coupling and nipple. In reinforced hose on inner sleeve layer cylindrical groove is made in reduction zone, and nipple is equipped with cylindrical ledge opposite sleeve groove. During reduction, the nipple cylindrical projection enters the cylindrical groove on the reinforced hose inner layer, creating zones of the sheared layer of increased pressure and the sealing zone.
EFFECT: invention can be used in transport, automotive, oil and other industries.
