A two-piece corner tie includes first and second tie halves which are removably connected together. The first tie half includes forward and rearward form panel retainers for holding form panels in upright spaced apart parallel relationship. The second tie half is preferably identical to the first tie half, and retains a second pair of form panels in upright spaced apart parallel relationship. The tie halves are connected by a pair of pins journaled through co-axial sleeves, to retain a first pair of form panels at a predetermined angle relative to a second pair of form panels, to thereby form a corner.
