Zusammenfassung:	The invention relates to a positive locking fastener comprising: a screw (1) having a radial hole (120) at a threaded portion (12); a nut (2) having a tightening portion (21); a cap (3); and a pin (4). The cap has a locking portion (31) intended to cover the threaded portion and a blocking portion (30) intended to engage with a tightening portion of the nut.The blocking portion comprises at least one pair of diametrically opposed openings (32) suitable for allowing a pair of openings to be aligned with the radial hole, in order to allow the pin to be inserted and thus lock the fastening regardless of the relative position of the nut with respect to the screw. The invention also relates to a method for implementing the fastener according to the invention.
