Abstract: The invention relates to a method of fixing a wear element (2) on the front edge of a support (1) using fixing means, where the wear element (2) comprises two arms (3) with first through openings (4) and the support (1) has a second through opening (5) sandwiched between the first through openings (4). The fixing means comprise a C-shaped first body (6), a wedge (14), ratchet means (24) between both and a second body (8), which are housed in the openings in an assembled position. The method consists of positioning the first body (6) and the second body (8) in the openings, inserting the wedge (14) between both, positioning a screw (21) between the wedge (14) and the second body (8) and screwing it in such a way that the wedge (14) moves with respect to the second body (8) and the first body (6) until the wedge (14) reaches its assembled position, and at least partially unscrewing the screw (21) and removing the screw (21) from the fixing means.

Abstract: A fixing device for fixing a wear or protection element on a shovel of an earth moving machine and the corresponding fixing system and method. Fixing device for fixing a wear or protection element (1) on a shovel (3) of an earth moving machine that comprises a stop, which is formed by a lower half-stop (7) and an upper half-stop (9) attached to one another by a screw (11), with a lower portion (31) suitable for being housed in a housing (17) arranged on a base (5) fixed to the shovel (3). Both half-stops can be separately introduced in the housing (17) through an opening (19) arranged on the upper face (21) of the wear element (1). The assembly formed by both half-stops has a plan view exceeding the perimeter of the plan view of the opening (19). The upper half-stop (9) is not in contact with the front wall (29).
