Device for a double hose structure with an inner main hose and an outer cover hose defining an annular space giving buoyancy in water. At least one end is provided with a coupling member forming a mount for the main hose and the cover hose which at a free end merges into a threaded portion for connecting the hose assembly to an auxiliary connection. The coupling member comprises an inner coupling sleeve connected to one end of the main hose and an outer coupling sleeve connected to the cover hose, the inner and outer coupling sleeves being mutually connected forming a liquid tight termination of the annulus by a ring-shaped plate. The plate is attached with screws through holes only to the outer sleeve, the plate being forced against a shoulder of the inner coupling sleeve by a ring nut with internal threads matching external threads on the inner sleeve.
