1. A central fastening system for fastening a structure of a wing of an aircraft to a structure of a pylon of said aircraft, said central fastening system having a longitudinal direction, said central fastening system comprising:
a first central fitting configured to be as one with the structure of the wing and having a first port-side clevis and a first starboard-side clevis, wherein each first clevis has a bore with an axis parallel to the longitudinal direction,
a second central fitting configured to be as one with the structure of the pylon and having a second port-side clevis and a second starboard-side clevis, wherein each second clevis has a bore with an axis parallel to the longitudinal direction,
a first connection system and a second connection system, each connection system having a third clevis and a fourth clevis, wherein each third and fourth clevis has a bore with an axis parallel to the longitudinal direction,
wherein the third clevis of the first connection system is mounted articulated with the first port-side clevis of the first central fitting at a first articulation point on a port side,
wherein the third clevis of the second connection system is mounted articulated with the first starboard-side clevis of the first central fitting at a first articulation point on a starboard side,
wherein the fourth clevis of the first connection system is mounted articulated with the second starboard-side clevis of the second central fitting at a second articulation point on the starboard side, and
wherein the fourth clevis of the second connection system is mounted articulated with the second port-side clevis of the second central fitting at a second articulation point on the port side, and
for each articulation point, a pin mounted in the bores of the corresponding clevises.
