Abstract
An article of manufacture for fixing the sides of a form with respect to each other is disclosed, which article consists of a unitary elongated metal member of generally Z-shape configuration having generally parallel end portions joined by an intermediate diagonal portion. Specific structural features of the article are described which provide improved resistance to vertical and horizontal shear forces acting on the form sides in addition to resisting transverse forces which tend to move the form sides toward or away from each other.
