Abstract
A retaining wedge for concrete forms has a tapered body of generally trapezoidal or triangular configuration. Oppositely diverging side edges of the body are provided with alternating peaks and valleys so as to present a number of detent-like depressions that encourage a firm and secure gripping action when the wedge is driven into the retaining slot of a locking pin that interconnects a pair of adjacent form panels. The peaks and valleys along each edge are presented by alternating convex and concave intersections between successive edge portions that slope outwardly at different angles from one another. Although certain portions of the edge slope outwardly at a higher angle than others, no edge portions slope inwardly toward the longitudinal axis of the wedge body. Consequently, the wedge is constantly tapering over its full length from one end to the other. A long, slender tip of the wedge facilitates insertion and fast starts.
