An assembly having an articulation spindle mounted in a first sleeve inserted into a first arm of a clevis and in a second sleeve inserted into a second arm of said clevis. The assembly comprises a blocking device which comprises a cylindrical stop housed in an extension of the second sleeve and comprising a front face against which a second end of the articulation spindle can come to bear, and a bolt-and-nut able to adopt a locked state, in which it passes through the stop and the extension so as to immobilize the stop in the extension, and an unlocked state, in which it does not pass through the stop and allows the stop to be removed from the extension.

1. An assembly comprising: an articulation spindle mounted in a first sleeve inserted into a first arm of a clevis and in a second sleeve inserted into a second arm of said clevis, said first sleeve comprising an inner shoulder which projects into said first sleeve and which acts as a stop for a first end of said articulation spindle, wherein the first sleeve and the second sleeve are coaxial on an axis, anda blocking device configured to act as a stop for a second end of said articulation spindle, the blocking device comprising: a cylindrical stop which is housed in an extension of the second sleeve and comprising a front face acting as a stop for the second end of the articulation spindle, anda bolt-and-nut configured to adopt a locked state, in which the bolt passes through the stop and the extension so as to immobilize the stop in the extension and an unlocked state, in which it does not pass through the stop and allows the stop to be removed from the extension, and wherein the bolt comprises a shank that has a longitudinal axis perpendicular to the axis of the sleeves. 2. The assembly as claimed in claim 1, wherein the stop comprises a first cylindrical portion with an external diameter substantially equal to an internal diameter of the extension and a second cylindrical portion whose diameter is smaller than that of the first portion. 3. The assembly as claimed in claim 2, wherein the stop and the extension each have lengths which are selected such that, when the assembly is assembled, the second portion of the stop is arranged at least partially outside the extension. 4. The assembly as claimed in claim 1, wherein the stop comprises at least one through passage for housing part of the bolt-and-nut. 5. The assembly as claimed in claim 4, wherein each through passage is arranged in a transverse plane. 6. The assembly as claimed in claim 1, wherein the extension comprises at least one pair of orifices configured so as to receive the bolt-and-nut, the orifices of each pair being diametrically opposite one another and arranged in a transverse plane. 7. The assembly as claimed in claim 6, wherein the extension comprises, on an outer surface thereof, flattened portions which extend around each orifice. 8. The assembly as claimed in claim 1, wherein the bolt-and-nut comprises a bolt, a slotted nut and a split pin passing through the bolt. 9. An aircraft comprising: an assembly comprising: an articulation spindle mounted in a first sleeve inserted into a first arm of a clevis and in a second sleeve inserted into a second arm of said clevis, wherein the first sleeve and the second sleeve are coaxial on an axis, said first sleeve comprising an inner shoulder which projects into said first sleeve towards the axis and which acts as a stop for a first end of said articulation spindle, anda blocking device configured to act as a stop for a second end of said articulation spindle, the blocking device comprising: a cylindrical stop which is housed in an extension of the second sleeve and comprising a front face acting as a stop for the second end of the articulation spindle, anda bolt-and-nut configured to adopt a locked state, in which it passes through the stop and the extension so as to immobilize the stop in the extension and an unlocked state, in which it does not pass through the stop and allows the stop to be removed from the extension, wherein the bolt-and-nut comprises a bolt and a nut, wherein the bolt comprises a head at a first end and a shank extending away from the head to a second end in a direction perpendicular to the axis of the sleeves, the second end being configured to receive the nut,an engine, anda wing,wherein the assembly connects the engine to the wing. 10. The assembly as claimed in claim 1, wherein said inner shoulder projects into said first sleeve toward the axis. 11. The assembly as claimed in claim 1, wherein the bolt-and-nut comprises a bolt and a nut, wherein the bolt comprises a head at a first end and a second end configured to receive the nut. 12. An assembly comprising: an articulation spindle mounted in a first sleeve inserted into a first arm of a clevis and in a second sleeve inserted into a second arm of said clevis, wherein the first sleeve and the second sleeve are coaxial on an axis,an inner shoulder disposed at an end of said first sleeve and wherein the inner shoulder precludes the passage of the articulation spindle out of the first sleeve, anda blocking device configured to act as a stop for a second end of said articulation spindle, the blocking device comprising: a cylindrical stop which is housed in an extension of the second sleeve and comprising a front face acting as a stop for the second end of the articulation spindle, anda bolt-and-nut configured to adopt a locked state, in which it passes through the stop and the extension so as to immobilize the stop in the extension, and an unlocked state, in which it does not pass through the stop and allows the stop to be removed from the extension, and wherein the bolt-and-nut comprises a bolt and a nut, wherein the bolt comprises a head at a first end and a shank extending away from the head to a second end configured to receive the nut, and wherein a longitudinal axis of the shank intersects with the axis of the sleeves. 13. The assembly as claimed in claim 12, wherein the stop comprises a first cylindrical portion with an external diameter substantially equal to an internal diameter of the extension and a second cylindrical portion whose diameter is smaller than that of the first portion. 14. The assembly as claimed in claim 13, wherein the first cylindrical portion comprises, on an outer surface thereof, flattened portions. 15. The assembly as claimed in claim 12, wherein the second end of the shank comprises a through passage. 16. The assembly as claimed in claim 15, further comprising a split pin extending through the through passage. 17. The assembly as claimed in claim 16, wherein the split pin extends through the through passage in a direction parallel to the axis of the first sleeve and the second sleeve. 18. The assembly as claimed in claim 16, wherein the split pin passes through the nut. 19. The assembly as claimed in claim 12, wherein the shank of the bolt passes through the extension and the stop. 20. The assembly as claimed in claim 19, wherein the extension includes at least two orifices for the shank, and wherein the stop includes at least two orifices for the shank.
