The tool (1) has a connection part (3) for fixing the tool on a corresponding support (2), and an active part (4) exposed to a wear action by contacting with ground during an execution of a working operation of the ground. The connection part has a position stop (6) engaged in a corresponding opening (7) arranged in the support. The stop is configured in a manner to uniquely counter the efforts resulting from the working operation, where the stop is formed in the thickness of the support.
