摘要：A concrete forming panel system having at least two rectangular panelswherein each panel has a pair of spaced apart sidewalls. Each panel has at least one

opening along each sidewall and the panels are adapted to be positioned in a side-by-side relationship so that one sidewall of each panel abuts against the sidewall of theadjacent side panel and, upon doing so, the opening in one sidewall of the first panelregisters with the opening in the abutting sidewall of its adjacent side panel. Anelongated pin is slidably mounted to each panel and movable between an extendedposition in which the pin extends through registering openings on adjacent panels, and aretracted position in which the wall pin is retracted from said registering openings. Alatch is pivotally mounted to the pin so that, with the wall pin in its extended position, thelatch pin extends through a transverse opening in the pin to lock the sidewalls of theadjacent panels together against relative movement.
