Abstract
The invention is directed to a safety release disconnection for a fluid conduit. The connection includes a pin and a U-shaped slot with an ejector spring adjustably biased by a loading nut. Check valves are provided in both connection elements and are opened by contact or interfacing of the valves. A rigid moment arm points in a direction perpendicular to the direction that a vehicle pulls away from the filling stand. A pull away while the system is connected to the vehicle will trigger the safety release disconnection.
