1. An aircraft nacelle comprising a door that moves relative to a stationary part, and a connecting device that makes it possible to limit the relative displacement between said door and said stationary part in a direction that corresponds to a primary direction of air flow outside of the nacelle during flight, said door being positioned downstream of said stationary part in said direction, said connecting device comprising an indexer connected to the door, said indexer comprising an attachment surface and at least one attachment element, and said connecting device further comprising at least one stop that is connected to the stationary part by a surface perpendicular to said direction and against which said indexer can rest in such a way as to limit movement of said indexer in said direction, said at least one attachment element being oriented radially of said direction and positioned upstream from said at least one stop in said direction, said at least one stop comprising a surface facing said door which is positioned on a line, parallel to said direction, which passes through said at least one attachment element and positioned essentially at the attachment surface of the indexer. 2. The aircraft nacelle according to claim 1, wherein the connecting device comprises a female part with two stops that are separated from one another in said direction and which are configured to limit movement of the indexer in said direction, and wherein said at least one attachment element is positioned between said two stops. 3. The aircraft nacelle according to claim 2, wherein the female part comprises a plate extending in said direction and comprising an opening sized to receive said indexer, said plate having a thickness less than 6 mm. 4. The aircraft nacelle according to claim 3, wherein the plate is connected to the stationary part using brackets and connecting elements that fasten said brackets to the stationary part and to said plate. 5. The aircraft nacelle according to claim 2, wherein the indexer is connected to an intermediate plate using said at least one attachment element, said intermediate plate being connected to the door by one or more further attachment elements. 6. The aircraft nacelle according to claim 1, wherein the female part comprises a plate extending in said direction and comprising an opening sized to receive said indexer, said plate having a thickness less than 6 mm. 7. The aircraft nacelle according to claim 6, wherein the plate is connected to the stationary part using brackets and connecting elements that fasten said brackets to the stationary part and to said plate. 8. The aircraft nacelle according to claim 1, wherein the indexer is connected to an intermediate plate using said at least one attachment element, said intermediate plate being connected to the door by one or more further attachment elements. 9. The aircraft nacelle according to claim 8, wherein the one or more further attachment elements have a shearing resistance that is different from that of said at least one attachment element. 10. The aircraft nacelle according to claim 9, wherein said intermediate plate has an approximately triangular shape, said indexer being attached near an apex of said intermediate plate, said one or more further attachment elements being along an opposite side of said intermediate plate. 11. The aircraft nacelle according to claim 8, wherein said intermediate plate has an approximately triangular shape, said indexer being attached near an apex of said intermediate plate, said one or more further attachment elements being along an opposite side of said intermediate plate. 12. The aircraft nacelle according to claim 1, wherein the door is made of a composite material.
