The invention is directed to a guide bar for the saw chain of a motor-driven chain saw and includes a base body section on which a nose assembly section for the saw chain is releasably attached. The nose assembly section is attached to the base body section by means of a releasable lock which is not destroyed in order to effect a separation of the two sections. The lock includes an eccentric cam which is rotatable about an axis transverse to the plane of the guide bar. The cam is in contact engagement with a wall of a bore in the guide bar when the cam is in the locked position. |
