The wooden block is the other part of the tool and the other end of the aluminum strap is connected to the bottom of the wooden block creating a sort of loop which wraps from the block, around the leading edge cover to the lever arm.

This brace is functioning as a drag wire in the compression of the component and as an anti drag wire in the tension of the component.
