An anchoring harpoon (1) intended for an aircraft, capable of cooperating with an anchoring grate (2) of a platform. The harpoon comprises a jack means (3) which includes cylinder means (4) containing mobile piston means (5) provided with a rod (6) that extends beyond the cylinder means, the free end of which includes a harpoon head (7). The harpoon head hooks into 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 harpoon is characterised in that the jack means are connected to a pressurised fluid source (30) by means of control means (31) and in that the pressurised fluid source includes a consumable CO2 gas cartridge (30).
