What is claimed is: 1. 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one of said mortises such that said latch fixes the shutter with respect to said body, and being able to assume a withdrawn position in which its catch is clear of said mortise, each latch being elastically urged towards said operating position, each latch having a maneuvering portion adapted to cooperate with the edge of said spout in order for said latch to be driven to the withdrawn position by said spout when it meets the maneuvering portion during a thrusting movement into the end piece (10), the maneuvering portion of each latch being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. 2. An end piece according to claim 1, wherein said shutter is movable parallel to a wall in which said passage aperture is provided, said shutter being situated in front of said wall, the maneuvering portion of each said latch being situated in front of said shutter in said operating position. 3. An end piece according to claim 2, wherein said body has a wall situated in front of said shutter, said mortises being provided in said wall situated in front. 4. An end piece according to claim 1, wherein each said latch is of elastic metal wire. 5. An end piece according to claim 4, wherein each said latch comprises an elbow portion forming said maneuvering portion. 6. An end piece according to claim 5, wherein said elbow portion is connected by a first end to said catch. 7. An end piece according to claim 6, wherein said catch is in the general form of an inverted U. 8. An end piece according to claim 6, wherein said elbow portion is connected by a second end to a straight portion. 9. An end piece according to claim 8, wherein said straight portion is connected by a first end to said elbow portion, referred to as the first elbow portion, and by a second end to a second elbow portion. 10. An end piece according to claim 9, wherein, in operating position, said first elbow portion is oriented in a generally vertical plane whereas said second elbow portion is oriented in a generally horizontal plane. 11. An end piece according to claim 9, wherein the two latches are joined by an intermediate portion, with the end of each said second elbow portion that is remote from said straight portion being connected to said intermediate portion. 12. An end piece according to claim 1, wherein the two latches have a similar arrangement, the shape of one being the mirror image of the shape of the other. 13. An end piece according to claim 1, wherein said body comprises a back wall in which said passage aperture is provided and a front wall in which an aperture for entry into the protection assembly is provided, said shutter and said latches being arranged between said back wall and said front wall. 14. An end piece according to claim 13, wherein said back wall is part of a cup whereas said front wall is part of a cover added on said cup. 15. An end piece according to claim 1, wherein said body comprises, bordering said passage aperture, a set of ribs arranged side by side and each having an inclined side of which the base is located at the edge of the passage aperture, said sides being inclined forwardly and outwardly, whereas said shutter has a set of ribs each having an inclined side, the inclined sides of the ribs of the body and of the ribs of the shutter facing each other in said obturating position. 16. An end piece according to claim 1, wherein said body is provided with a duct for evacuation of liquid that may have entered therein. 17. An end piece according to claim 1, wherein it comprises, behind said protection assembly, an obturating assembly. 18. An end piece according to claim 17, wherein said obturating assembly has a flap valve.
