Zusammenfassung:	A self-locking and anti-loosening fastener, consisting of a limiting nut (1), a limiting bolt (3), and a limiting sleeve locking nut (2). A limiting pin (3-2) is machined at the front end of the limiting bolt (3); threads matched with the limiting bolt (3) are machined on the inner side of one end of the limiting nut (1); a limiting sleeve (1-3) matched with the contact surface of the limiting pin (3-2) is machined on the inner side of the other end of the limiting nut (1); limiting sleeve locking threads (1-4) and a limiting sleeve side wall gap (1-2) are machined on the outer side; the limiting sleeve locking nut (2) is matched with the limiting sleeve locking threads (1-4). L'invention concerne un élément de fixation autobloquant et anti-desserrage constitué d'un écrou de limitation (1), d'un boulon de limitation (3) et d'un écrou de blocage (2) à manchon de limitation. Une broche de limitation (3-2) est usinée au niveau de l'extrémité avant du boulon de limitation (3); des filetages adaptés au boulon de l
