For use in securing a concrete form board, the form pin of the invention includes a clip having first portion substantially in the shape of a cylinder to be forced onto one end of a steel bar driven into sand, shale or clay and of an inside diameter substantially equal to the diameter of the bar, along with a tab portion having a plurality of spaced apertures extending through opposing planar surfaces to receive nails or screws to be removably secured to the concrete form board, and with the tab portion extending outwardly of the cylindrical portion a distance to allow manual grasping thereof in freeing the steel bar from the ground. In a preferred embodiment of the invention, the steel bar consists of a rebar having a plurality of rims circumscribing its outer surface, in cooperating with the cylindrical portion of the clip in limiting spinning, or otherwise movement of the clip once forced upon the rebar for use, especially when the clip is constructed of a deformable plastic.
