A device for securing at least two elements together by means of a screw (3) and a transfer nut (4) adapted to be engaged in the recessses (1a, 2a) of said elements (1, 2) is characterized in that the transfert nut (4) includes a nut plate (6) having a threaded hole (7), on either side of which are located areas (8, 9) for the passage of the arms (10, 11) of a fastening unit (12) having a generally flare-shaped U cross section. The intermediate portion (13) of the latter includes a hole for the passage (14) of the screw (3) opposite the threaded hole (7) of the nut plate (6) and is adapted to be applied against a stop surface of the screw (3) or of the element (1) on which said screw rests, such that the nut plate causes the arms (10, 11) of the fastening unit (12) to be spaced apart and abuts on a contact surface of the other element (2) during screwing, in order to secure the elements together.
Ce dispositif de fixation d'au moins deux organes l'un sur l'autre, à l'aide d'une vis (3) et d'un écrou transfert (4), adaptés pour s'engager dans des évidements (1a, 2a) desdits organes (1, 2), est caractérisé en ce que l'écrou transfert (4) comporte une plaque d'écrou (6) comprenant un trou taraudé (7) de part et d'autre duquel sont ménagées des zones (8, 9) de passage de branches (10, 11) d'un organe d'accrochage (12) de section de forme générale en U évasé, dont la portion intermédiaire (13) comporte un trou de passage (14) de la vis (3) en regard du trou taraudé (7) de la plaque d'écrou (6) et est adaptée pour s'appuyer contre une surface de butée de la vis (3) ou de l'organe (1) sur lequel s'appuie cette vis, de manière que la plaque d'écrou provoque un écartement des branches (10, 11) de l'organe d'accrochage (12) et leur venue en butée contre une surface d'appui de l'autre organe (2) lors du vissage, pour fixer les organes l'un sur l'autre.
