Abstract
The present invention relates to a method of attaching a wear part to an earth-working tool and a thereto adapted wear part. Characteristic of the invention is that the parts are joined together by means of a press fit which in turn is blocked by means of pretensioned resilient locking means which when fitted in place continually act upon the parts in the direction of interconnection. The invention provides a play-free and reliable interconnection for the tool and wear part, which is also very easy to remove.
