Adjacent the free end of a flexible hose (22) an external thread (20) of elastomeric material is bonded or vulcanized to the external surface (21) of hose (22). A sleeve (1) is threaded onto and adhesively bonded to the external thread (20). The sleeve (1) consists of a sleeve body (2) of plastic or elastomeric material and a metallic ring (3) preferably of spring steel. The ring (3) is molded into the sleeve body (2). Part of its surface constitutes a shoulder for engagement by a cam of a coupling lock. The sleeve (1) is cheaper to manufacture and more durable than metallic sleeves.
