Claim:
1. A high-pressure fluid conduit adapted for connection between a high-pressure fluid source and a high-pressure fluid container, said high-pressure fluid conduit comprising: a hose unit having a first end and a second end; a first housing adapted for connection to a high-pressure fluid source and having: (a) a first fluid opening through which high-pressure fluid from the high-pressure fluid source enters said first housing, (b) a second fluid opening through which high-pressure fluid from the high-pressure fluid source leaves said first housing, and (c) a cavity between said first fluid opening in said first housing and said second fluid opening in said first housing; a second housing abutting said first housing and having: (a) a first fluid opening aligned with said second fluid opening of said first housing and through which high-pressure fluid leaving said first housing enters said second housing, (b) a second fluid opening through which: (c) a cavity between said first fluid opening in said second housing and said second fluid opening in said second housing; a coupling: (a) for: (b) having a weakened break-away section that: a valve seat at said second fluid opening in said first housing; a valve seat at said first fluid opening in said second housing; a first valve body pivotally mounted in said cavity of said first housing and movable between: (a) a first position to permit the flow of the high-pressure fluid from the high-pressure fluid source through said first housing, and (b) a second position against said valve seat in said first housing to prevent high-pressure fluid leaving said first housing; a second valve body pivotally mounted in said cavity of said second housing and movable between: (a) a first position to permit the flow of the high-pressure fluid from the high-pressure fluid source through said second housing, and (b) a second position against said valve seat in said second housing to prevent the flow of high-pressure fluid from said hose unit leaving said second housing; and a valve control: (a) retaining said first valve body in its first position and said second valve body in its first position, and (b) selectively moving said first valve body towards its second position and said second valve body towards its second position in response to fracture of said coupling and separation of said parts of said coupling.
