Connecting device for form panels

A connecting device for interconnecting two juxtaposed upright form panels used in forming a concrete wall, said form panels having adjacent mating edges between which an edge connecting plate is interposed tightly and removably, said connecting device comprising:

• first and second mounting plates secured respectively to said form panels adjacent to said mating edges of said form panels, said first mounting plate being formed with a through-hole, said second mounting plate being formed with a first screw hole which is aligned with said through-hole in said first mounting plate and a second screw hole on one side of said first screw hole;
• a pair of guide rods, each of which having an end portion extending through said first mounting plate and secured to said second mounting plate so as to permit relative lateral movement between said form panels;
• a driving screw having a threaded shank portion which extends through said through-hole in said first mounting plate and which engages threadably said first screw hole in said second mounting plate, and a head portion which is sized to prevent extension thereof through said through-hole in said first mounting plate;
• and
• a positioning screw having a threaded shank portion extending threadably through said second screw hole in said second mounting plate, and abutting against said first mounting plate;
• whereby, when said edge connecting plate is removed and said positioning screw is loosened to move said positioning screw away from said first mounting plate, rotation of said driving screw in a predetermined direction causes movement of said first mounting plate toward said second mounting plate so as to facilitate stripping of said form panels from said concrete wall.
