Zusammenfassung:	System for plugging the top (2) of a fuel tank filler pipe, the said system comprising a stopper (3) allowing the pipe to be opened automatically via the act ion of a fuel dispensing nozzle, this stopper (3) being: retractable under the action of a thrust directed against it along an axis parallel to the axis of the top (2) of the pipe; secured to a return spring (6) keeping it in the closed position; the said system also comprising a moving ring (8) able to prevent the movement of the stopper (3) via a bayonet system, and in which the movement of the bayonet system between opened and closed (or vice versa) is governed by a specific actuator and consists of a progressive helical movement that progressively compresses (or decompresses) a seal (11) affixed between the stopper (13) and the top (2) of the pipe.
