Claim:
An end piece for a fuel filler pipe of a vehicle provided for allowing the passage to said pipe of a supply spout exclusively if the outer diameter of said spout is at least equal to a predetermined threshold, the end piece comprises a protection assembly comprising: a body having an aperture for spout passage to said pipe; a shutter movable with respect to said body, able to assume an obturating position in which it conceals said passage aperture and a freeing position in which it does not conceal said passage aperture, said shutter being elastically urged towards said obturating position, said body and said shutter being adapted to cooperate with said spout in order for the shutter to be driven towards the freeing position by said spout, during a thrusting movement of the latter into the end piece, when it meets the shutter; and two latches mounted on the shutter and two mortises belonging to the body, each latch having a catch and, when the shutter is in said obturating position, being able to assume an operating position in which its catch is engaged in a respective one of said mortises such that said latch fixes the shutter with respect to said body, and being able to assume a withdrawn position in which its catch is clear of said mortise, each latch being elastically urged towards said operating position, each latch having a maneuvering portion adapted to cooperate with the edge of said spout in order for said latch to be driven to the withdrawn position by said spout when it meets the maneuvering portion during a thrusting movement into the end piece ( 10 ), the maneuvering portion of each latch being separated from the maneuvering portion of the other latch by a free space having a length equal to said predetermined threshold.
