Abstract
A system for locking a closure mechanism for a fuel-tank filler pipe covered by a fuel flap, the closure mechanism includes a shutter allowing automatic opening of the pipe via action of a fuel-dispensing nozzle, this shutter being retractable through action of thrust directed against it along an axis parallel to the axis of the pipe head and integral with a return spring allowing it to be held in the closed position. The system includes a lever integral with the closure mechanism and having the effect of locking/unlocking it, depending on its position, and a lever arm, integral with the fuel flap, that can act effectively on the lever only to lock the mechanism when it is unlocked and the fuel flap is being closed.
