Fixing device for fixing a wear or protection element on a bucket of an earth moving machine and corresponding fixing method and wear or protection system

A fixing device for fixing a wear or protection element on a bucket of an earth moving machine, comprising:

• a base, where said base comprises a housing with a front wall and a rear wall, and where said rear wall has an access extending from said housing and defining a longitudinal axis,
• a stop, with a lower part suitable for being housed in said housing,
• a screw, with a first end provided with a head and a second end, and
• elastic means,
• the lower part of said stop being housed in said housing and said screw going through said access in a mounted position and one of said first end or second end being fixed on said stop, such that the other one of said first end or second end is located on the side of access opposite housing, and said elastic means are arranged between
• [a] said head and said access, when said second end is fixed on said stop, or
• [b] a nut arranged on said second end and said access, when said first end is fixed on said stop,
• and said elastic means are partially compressed, said elastic means having a length of value L0 in the direction of said longitudinal axis when they are fully compressed,
• said stop having a front face opposite said front wall and a rear face opposite said rear wall in said mounted position, an elastic force of said elastic means pushing said rear face towards said rear wall, and the distance between said front face and said front wall in the longitudinal direction having a value D1, the distance in the longitudinal direction, in said mounted position, between
• [a] said head and said access, when said second end is fixed on said stop, or
• [b] said nut arranged on said second end an said access, when said first end is fixed on said stop,
• having a value D2,
• and where D2−L0>D1 in said mounted position.
