<p>The coupling (10) has an interference fit (30) including ribs (31, 32) aligned to a high-pressure hose (20) at an inner jacket. A metal insert (22) is pressed between a hose nipple and the interference fit and released from plastic casings (21, 23) i.e. rubber coating, in a securing portion (A). A metallic tear-off protection ring (50) is fixed at the nipple and provided in the portion. Outer side of the ring is formed with a circumferential groove (55). The groove is located opposite to the ribs at interference fit, and receives material of the insert of the hose during radial compression.</p> |
