This invention relates to a device for a bucket of a digging machine, which in a usual way comprises a hydraulically operable arm, which is arranged to be detachably fastened on the bucket, the outer portion of the arm comprising a plate-formed means, which is intended to be detachably applied on an outer delimitation surface of the bucket, and a plurality of shim means being fastened on the delimitation surface and accordingly positioned between the bucket and the plate-formed means of the arm of the digging machine. According to the invention the device comprises the combination of the following features: each shim means (5) has a rectangularly or squarely designed frame (6), which is fastened on the delimitation surface (3) of the bucket (4) in a suitable way and comprises two parallel side portions (7, 8) and a third portion (9), which has a transverse direction in relation to the two first portions, and which connects the one pair of ends of the side portions (7, 8) with each other; a spacing piece (10) is insertably arranged between the side portions (7, 8) of the frame (6) and is designed in that way that it is movable within limits in a direction (V), which is essentially perpendicular to the plane of the delimitation surface (3) and accordingly the frame (6), a space being created between the delimitation surface (3) and the spacing piece (10), into which space one or more insert plates (18) are insertable; the other pair of ends of the side portions (7, 8) is connected by a detachable back piece (15), which accordingly prevents the spacing piece (10) and possible insert plates (18) from coming loose from the frame (6) of the shim means (5).
