Capture pin for a locking hook

An aircraft landing gear, comprising a landing gear provided with a yoke supporting a spindle on which is mounted a capture pin to be hooked by a hook of a locking box to be mounted on a structure of an aircraft to immobilize the landing gear in a given position with respect to said structure;

• the capture pin comprising a body provided with a longitudinal opening enabling the capture pin to be mounted on the spindle, and an outer surface of revolution having a central portion having a convex profile to cooperate with the hook,
• wherein the central portion of the outer surface is formed on a central ring which is mounted so as to rotate freely on a central portion of the body, and
• wherein the outer surface of revolution of the capture pin comprises two side portions, one on either side of the central portion of the outer surface of revolution, the two side portions extending with the central portion of the outer surface of revolution according to a fracture-free convex profile.
