1. An aircraft engine attachment including at least one assembly comprising:
a first part,
a second part, and
a connecting device connecting the first and second parts,
the connecting device including:
first and second articulation elements accommodated in first and second holes through the first and second parts, and
first and second links, connecting the first and second articulation elements, positioned on respective opposite sides of the first and second parts,
the first link having a planar internal face oriented toward the second link, the second link having a planar internal face oriented toward the first link,
wherein the connecting device comprises:
an interleaved stiffener positioned between the first and second links, having a first contact face oriented toward the first link and a second contact face oriented toward the second link, parallel to the first face, the first and second contact faces being planar and separated by a distance equal to that separating the first and second links, the planar internal faces of the first and second links being held against the first and second planar contact faces of the interleaved stiffener,
the interleaved stiffener including:
a body of parallelepiped shape,
a first yoke, connected to the body, cooperating with the first part, and
a second yoke, connected to the body at an end opposite the first yoke, cooperating with the second part,
 the body, the first yoke and the second yoke forming a single part,
wherein the interleaved stiffener limits bending of the first and second links when the first and second links are loaded in compression,
wherein the interleaved stiffener enables a distance between the first and second links to remain constant in the presence of compression forces and limits transverse bending of the first and second links.
