Abstract
The invention relates to a replaceable end bit for a soil-working tool, which end bit is retained by friction and wherein, at its trailing edge, the end bit is provided with one or more openings that is/are oriented rearwardly relative to the end bit and for receiving couplers from a holder part. The openings may have rounded faces, and the faces may face towards each other. The distance between the rounded faces is increased with the distance from the trailing edge of the end bit. The invention also relates to a holder part for a replaceable end bit for a soil-working tool, which end bit is retained by friction, and wherein the holder part is provided with pairs of protruding couplers, which protruding couplers are provided with a space, where the distance between the two protruding couplers is reduced with the distance from their end faces.
