Abstract
An expansion plug including a cam lever with a securing portion, and a top plate with a flange. A first hole is centered in the securing portion and a second hole is centered in the flange. During engagement of the cam lever, the securing portion adjoins the flange, aligning the two holes. Thus, a lock may be inserted through both holes to securely fasten the cam lever to the top plate.
