The invention relates to an anchoring harpoon intended in particular for an aircraft, capable of cooperating with an anchoring grate of a platform, comprising jack means including cylinder means containing mobile piston means provided with a rod that extends beyond the cylinder means, the free end of which includes a harpoon head (7) that is hooked in the grate and comprises retaining fingers (8, 13, 14) that can be moved between a retracted position and an active position by control means (9). The invention is characterised in that the means (9) for controlling the movements of the fingers comprise 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 means.
