Abstract
A pin and wedge combination to couple adjacent panels of a concrete wall form together includes a self-retaining pin with a spring biased ball to temporarily retain the pin in the hole in the flange of the panel during assembly of a concrete wall form without adding significant weight to the associated components or the panels or requiring costly modifications to existing panels.
