Double hose device

A device for a double hose assembly (11) with an inner main hose (12) and an outer cover hose (13) arranged for assembly and disassembly and defining an annular space (14) providing the hose with buoyancy in water,

• the device having a coupling member (15) on at least one end (15) forming a mount for the main hose (12) and the cover hose (13), and having a free end that merges into a threaded portion (22) for connecting the hose assembly (11) to an auxiliary connection, the coupling member (15) comprising an inner coupling sleeve (16) which is tightly connected to one end of the main hose (12) and an outer coupling sleeve (18) which is tightly connected to the cover hose (13), the inner coupling sleeve (16) and outer coupling sleeve (18) being mutually connected to form a liquid tight termination of the annulus (14) via a ring-shaped plate (30), wherein
• the ring-shaped plate (30) is attached with a plurality of screws (25) through holes (29) only to the outer sleeve (18), the ring-shaped plate (30) being forced against a shoulder (20) of the inner coupling sleeve (16) by a ring nut (40) with internal threads that match external threads (21) on the inner sleeve (16) and the inner main hose (12) and the outer cover hose (13) are disassembled by unscrewing the ring nut (40).
