Abstract

A replaceable guide piece (10) for an extraction or coal plough (100) is provided. The replaceable guide piece (10) includes a generally U-shaped guide piece body (12) configured to be inserted into a guide claw (14) of the plough (100). A single recess (22) is formed in a central portion of a guide piece body (12) to extend at an angle (α) from an upper side of guide piece body (12) to a side surface of the same. A locking mechanism (24) is configured to engage with the single recess (22) to prevent movement of the guide piece (10) in the longitudinal direction after insertion of the guide piece (10) into the guide claw.
