Abstract: The invention relates to a hook latch (73) configured so as to lock and unlock a mobile structure on a fixed structure of a vehicle, said latch having an adapter (69) fitted with a hook (73) capable of fastening a keeper, a handle comprising a trigger, on the handle, a second pivot connection axis, on the trigger, at least one hook capable of fastening at least one protrusion (125) of a bracket (121) connected to the adapter, a third pivot connection axis, around which the handle and the adapter are guided in rotation in relation to each other, and characterised in that it comprises an adjustment device for adjusting the flushness of the upper surface of the handle in relation to the aerodynamic surface, said device comprising the bracket (121), a screw (129) capable of being screwed and unscrewed within a first tapped recess of the adapter.

Abstract: The invention relates to a quick-release fastener (100) of the ball-pin type, consisting of a tubular body (102) provided with a radial opening (108), an enlarged head (104), a rod (112) that can move axially within the body and through the head, a ball (110) capable of moving radially between a released position in which it rests in a reduced cross-section (132) of the rod (112) inside the body and a locked position in which it protrudes radially beyond the body through the radial opening (108), and a lever (114) that pivots about a pin (118), which lever includes at least one cam surface (142) that is in contact with the head. The rotational actuation of the lever draws the rod toward the head and causes the ball to move into the released position.

Abstract: The invention relates to a lock (100) comprising: -two substantially planar walls (101) bearing a first pivot connection axle (102) and a second pivot connection axle (103), the first and second axles being substantially perpendicular to the planes; -a catch (108) able to pivot about the first axle, the catch comprising a hook (109) able to catch a strike wire; -a pawl (111) able to pivot about the second axle, the pawl comprising a tooth (112) able to engage with at least one notch (113, 114) formed on the catch, when the lock is in what is known as the closed position; -a control lever (115) able to pivot about the second axle, the lever comprising a means (116) of driving the rotation of the pawl (111) about the second axle, the control lever comprising means (118, 119) for securing the closure of the lock.
