1. An assembly for an aircraft, the assembly comprising: an attachment pylon for an aircraft engine, the attachment pylon comprising a primary structure in a shape of a box section; andan engine attachment mounted on the attachment pylon, wherein the engine attachment provides a joint between the aircraft engine and the attachment pylon,wherein a body of the engine attachment is arranged on an outside of the primary structure,wherein the engine attachment comprises shackles that are articulated on the body of the engine attachment,wherein at least the body of the engine attachment has, at least at a first end, a first one-piece fitting comprising a first joining portion, on which one of the shackles is articulated, and a second joining portion, which is fixed within, at least partially, the primary structure, andwherein the engine attachment is a rear engine attachment. 2. The assembly according to claim 1, wherein the second joining portion is arranged between a lateral panel of the primary structure and an internal transverse stiffening rib of the primary structure. 3. The assembly according to claim 1, wherein the first joining portion is a clevis and the second joining portion is substantially flat. 4. The assembly according to claim 1, wherein the body of the engine attachment comprises, at a second end that is opposite the first end in a transverse direction of the assembly, a second one-piece fitting comprising a first joining portion, on which one of the shackles can be articulated, and a second joining portion, which is fixed within, at least partially, the primary structure. 5. The assembly according to claim 4, wherein the body of the engine attachment comprises a central beam, which is interposed between the first and second one-piece fittings fixed to the ends of the body of the engine attachment, on which one or more of the shackles can be articulated. 6. The assembly according to claim 5, wherein the central beam is produced in one piece with an internal transverse stiffening rib of the primary structure, the rib crossing a lower spar of the primary structure. 7. The assembly according to claim 5, comprising a device for taking up thrust forces, the device comprising: a support element fixed to the primary structure, the support element being located outside the primary structure;two lateral link rods for taking up thrust forces; anda spreader articulated on the support element, the two lateral link rods being articulated on opposite ends of the spreader, respectively. 8. The assembly according to claim 7, wherein the spreader is also mounted with play at both ends on connecting members that are integral with the central beam. 9. The assembly according to claim 7, wherein the support element is arranged in a recess in the central beam. 10. The assembly according to claim 7, wherein the assembly comprises a front engine attachment. 11. The assembly according to claim 10, wherein the rear engine attachment, the front engine attachment, and the device for taking up thrust forces together comprise an attachment for attaching the engine as an isostatic system for taking up forces. 12. The assembly according to claim 1, wherein the engine attachment comprises two lateral half-attachments, a first of the two lateral half-attachment being configured to only take up thrust forces oriented in a vertical direction of the assembly and a second of the two lateral half-attachments being configured to only take up thrust forces oriented in the vertical direction and in a transverse direction of the assembly. 13. An aircraft part comprising an assembly according to claim 1, a wing element from which the attachment pylon is suspended, and an engine fixed to the engine attachment. 14. An aircraft comprising at least one assembly according to claim 1. 15. A method for removing an engine fixed by an engine attachment assembly, the method comprising: providing an assembly for an aircraft, the assembly comprising: an attachment pylon for an aircraft engine, the attachment pylon comprising a primary structure in a shape of a box section; andan engine attachment mounted on the attachment pylon, wherein the engine attachment provides a joint between the aircraft engine and the attachment pylon,wherein a body of the engine attachment is arranged on an outside of the primary structure having the shape of the box section,wherein the attachment pylon comprises shackles that are articulated on the body of the engine,wherein at least the body of the engine attachment has, at least at one end, a one-piece fitting comprising a first joining portion, on which one of the shackles is articulated, and a second joining portion, which is fixed within the primary structure, andwherein the engine attachment is a rear engine attachment; and removing each of the shackles at at least one end thereof.
