A reusable indexing tab includes first and second interconnected wing portions which are pivotally connected along a hinge portion. Each wing portion includes a first panel which acts as a clamping jaw, a second panel which acts as an index tab, and a hinge portion connecting the first and second panels. In the preferred embodiment the wing portions are identical with one wing portion inverted to interconnect with the other wing portion. A clamping force is produced by forming a bend in each first panel generally midway between the upper and lower edges, with the upper edge bent rearwardly. The bias of the bends produces a clamping force between the first panels. A lock mechanism on the second panels will selectively maintain the wing portions in their clamped position. Preferably, a second bend is formed in each wing portion with each first panel bent rearwardly along the longitudinal connection with the associated hinge portion. The two bends in each first panel creates a strong clamping pressure when the wing portions are moved to the clamped position.
