Beschreibung
Zusammenfassung:	The invention relates to a fixing system for fixing a wear element (16) in the nose (19) of a support element of an earth moving machine by means of a pin (7) which is housed in an opening of the wear element and in an opening (25) in the nose, coaxial with the opening of the wear element. The system comprises a retainer (1), which is a sheet material with a flexible flange (3) extending towards the path of the pin when it is introduced in the openings, interrupting said path. The retainer is fixed to the wear element or to the nose. The flange is bent towards the direction of the pin when it is introduced in the openings. The pin has a blocking segment (13) with a step the riser (15) of which is oriented such that the flange abuts against the riser when attempting to remove the pin. For its removal, the pin must be rotated about its axis until the flange comes out of the step and is arranged in a segment in which the side surface of the pin extends continuously until the final end (10) thereof.
