Abstract: An element is provided which includes a control section connection end and a setting position end for enabling a setting of the filling mechanism, with automatic shut-off. The setting end includes a retaining portion. The retaining portion acts to retain the element associated with a gasoline filling mechanism, even after gasoline filling shut-off. The element includes a hole or opening. The opening formed in the device adaptor element receives a connection element. This arrangement is particularly useful for supporting keys or other functional devices such as a bell which may be connected with the automatic gas fill adaptor element device.
