Attachment device releasable under a load for a trapeze harness used in sailing

An attachment device releasable under load for a trapeze harness used in sailing, which comprises:

• a planar body secured to a harness bar, receiving a set of straps which a crew member can put on with the harness bar against his abdomen, the body being positioned in a longitudinal median plane of the bar and facing forward,
• a hook mounted pivotably on a front portion of the body about a pivot pin transverse to the body, this hook including a downwardly hooked curved portion on a front face under the pivot pin, and a depression on the rear face that opens downward,
• a hairpin spring of which two ends of branches, facing each other, are engaged in apertures of the body that are offset and thus tend to make the spring pivot forward, in such a way that a central part of the spring locks the hook by bearing on a depression of the point of the hook, and
• a lever hinged to the body about a pin parallel to the pin of the hook and located above the latter, having an upper portion above the pin facing upward and forward and a lower portion facing downward and rearward, whose lower end bears on a forward facing surface of the branches of the hairpin spring.
