The invention concerns a method and a device for locking on a threaded rod (T) a nut (E, E') pierced with an orifice (e) for a lockwire (2) comprising a washer (1) provided with a central orifice, with at least a peripheral orifice (10) for allowing through said lockwire (2) and an antirotation element (11) designed to co-operate with an element (M) with matching profile arranged on said rod (T). The invention is characterised in that said antirotation element (11) of the washer (1) consists of a flat rim designed to co-operate with a flat section provided on the rod (T) parallel to the generators, and the nut (E, E') orifice (e) emerges laterally on two adjacent surfaces.
