The safety device is for a power-driven saw chain, having a roughly rectangular and plate-type body, with drillings one behind the other in its lengthwise direction for hinge pins. A portion protruding from the body has a face bearing against the bottom of the cut made by the saw in the saw in the log etc. The device (12) has a widened portion (20) extending beyond one or both sides (47) of the body (13). This can be formed by a widened lengthwise edge on the body.
