Abstract
An anchoring harpoon intended in particular for an aircraft, capable of cooperating with an anchoring grate of a platform, includes jack elements including a cylinder element containing mobile piston elements provided with a rod that extends beyond the cylinder element, the free end of which includes a harpoon head (7) that is hooked in the grate and includes retaining fingers (8, 13, 14) that can be moved between a retracted position and an active position by control elements (9). The control element (9) for controlling the movements of the fingers include a control piston (18) which can slide inside the rod of the jack and which is associated with a bistable actuator (19) of the fingers, capable of moving between a retracted position and an active position in which the fingers are deployed with the application of successive pressure pulses in the jack elements.
