The invention provides a connecting duct for a fluid engine fuel, which is adapted to extend between at least two systems able to be moved in relation to each other, the preferably rigid ducts inherent in the systems being connected together by means of a flexible hose able to compensate for changes in the distance apart of the systems. As a flexible hose a safety hose connection (1) is provided, which comprises a flexible pressure line (2) adapted to carry the fluid and a flexible protective line (3) encasing the latter with a clearance as a cavity and furthermore at least one detecting (3), processing (6) and switching (7) element connected with the cavity (4) between the pressure line (2) and the protective line (3), such element being adapted to detect a change in the state of the cavity (4) and to react to same. |
