Abstract: At their lower edge (6) excavators are provided with a tooth arrangement consisting of two parts (1 and 2), one part (2) being attached to the bucket (6) and the other part (1) being exchangeable. The two parts (1 and 2) are held together by means of a male and female relationship and a transverse aperture (3 and 25) with a locking body (4). When the exchangeable part (1) becomes worn it may start to become unstable. The object of the present invention is to eliminate this drawback and this is achieved in that the locking body (4) comprises two opposing flat surfaces, provided with one or more spacers (15-20) intended to restrict approach of the two surfaces towards each other.
