Abstract: A concrete form apparatus and system for connecting opposing form sections at a desired distance from each other defining a space to receive poured concrete, the apparatus preventing the form section separation, the apparatus including a locking pin, form connector rotatably and releasably affixed to a form, and retainer affixed to arm defining a channel therein sized to be engaged within the slot whereby the locking pin is placed through corresponding holes in adjacent forms and engages a first form, extends through the relative distance between the forms, exits through a hole in the second form, and the channel of the retainer attached to the second form engages the locking slot on the locking pin maintaining a fixed distance between the forms and preventing form separation when pouring concrete. A system using the foregoing and also including clamps for affixing adjoining forms to one another is also claimed.
