摘要

The invention relates to a device for attaching a wear or protection element (5) to a shovel of a soil-shifting machine, comprising: a base (7) with a housing (15) having a front wall (17) and a rear wall (19) with a through-opening (21); a stop (9), with a lower part (25) housed in the housing (15); a screw (11) that passes through the opening (21), the end of said screw being fixed to the stop (9); and partially compressed elastic means (13) arranged between the screw (11) and the opening (21). When the elastic means (13) are fully compressed, the length thereof is L0. In a mounted position, the stop (9) has a front face (27) facing the front wall (17) where the distance between the two is D1 and the distance between said head and said opening (21) has a value of D2, and in the mounted position, D2 - L0 > D1 is satisfied.
