A retaining assembly is provided for a tensioning arrangement for adjusting the tension of the cutting chain in the chain saw. The retaining assembly includes a rotatable knob that operates in conjunction with the chain saw's engine chassis, clutch cover, and guide bar and is rotatable about an axis of rotation between a tightening position for holding the guide bar in place and a loosening position enabling the guide bar to be repositioned whereby the tension in the cutting chain is adjusted. A locking mechanism is provided for locking and unlocking the knob for rotational movement. When the locking mechanism is in a locking position, moveable engagement points of the locking mechanism extended beyond the confines of the knob and engage fixed engagement points.
