A high-pressure fluid conduit that conducts high-pressure fluid from a high-pressure fluid source to a high-pressure fluid container through a hose unit during open or normal operation. This high-pressure fluid conduit has a safety feature that is activated when the high-pressure fluid conduit fails due to exposure to a predetermined force. The safety feature closes off the flow of high-pressure fluid from the high-pressure fluid source and closes off the escape of high-pressure fluid from the hose unit that entered the hose unit during open or normal operation. In addition, when the hose unit fails, fluid flow from the high-pressure fluid source and high-pressure fluid flow from the high-pressure fluid container is prevented.
