An irretrievable nut, characterized by being formed by a slot perpendicular to its axis of rotation, which has the amplitude of one of its threads, and the depth to the center of its axis of rotation, being able to close its outer mouth by a stroke of a pliers, with which a divergence of the walls of said mouth is achieved and consequently a dislocation of its thread that makes its recoil impossible; can be performed only by express act, by opening the mouth by introducing a wedge to achieve its previous position.
