ABSTRACT:
A protective safety cover for a power transmission chain of a chain saw power head and an attachment for the power head, having at least two fins for engagement by the cover, is provided with two grooves adapted to frictionally engage the fins to secure the cover to the attachment. The grooves are curved until the fins are located therein so that upon location of the fins in the grooves the cover is resiliently deformed to correspond to the shape of the fins thereby enhancing the frictional engagement between the fins and grooves.
