An assembly for an aircraft having a wing and an engine pylon for mounting a jet engine beneath said wing, the engine pylon comprising:

• a primary structure forming a box and having a right-side lateral panel, a left-side lateral panel, an upper spar, a lower spar and a rear rib that closes the box at the rear,
• a first set of upper shackles and a second set of upper shackles, wherein the first set of upper shackles fastens, in use, the right-side lateral panel to a structural element of the wing, and wherein the second set of upper shackles fastens, in use, the left-side lateral panel to a structural element of the wing,
• a first set of lower shackles and a second set of lower shackles, wherein the first set of lower shackles fastens, in use, the right-side lateral panel to a structural element of the wing, and wherein the second set of lower shackles fastens, in use, the left-side lateral panel to a structural element of the wing,
• a fastening element secured to either the rear rib or the lower spar,
• a rear rod that connects the fastening element to a structural element of the wing, and
• a transverse shackle that connects the upper spar to a structural element of the wing, wherein a line connecting two centers of the transverse shackle is oriented transversely with respect to a longitudinal axis of the engine pylon,
• a reinforcing panel, at each join between a right-side lateral panel or a left-side lateral panel and a shackle of the first set or second set of upper or lower shackles, which is fastened along a height against the right-side lateral panel or left-side lateral panel and to which said shackle of the first set or second set of upper or lower shackles is also fastened.
