ABSTRACT:
A leakage preventive mechanism for flexible hoses through which is transferred fluid under a high pressure is disclosed. The mechanism comprises a rib made integral with a nipple portion of a nipple flange and circumferentially extending around said nipple portion. An end of a reinforcing layer embedded in the flexible hose passes over the rib and is wrapped around a bead wire arranged near the rib to form an inclined turn-back portion. A pair of rings are urged against the inclined turn-back portion of the reinforcing layer by means of bolts, whereby the inclined turn-back portion of the reinforcing layer functions as a packing for preventing the fluid from passing over the rib.
