  • Patent number: 9487961
    Abstract: The invention relates to a connecting device for formwork boards having a formwork lining and elements supporting the formwork lining for producing concrete structures, wherein the connecting device comprises two claws and a clamping means, particularly a wedge or a clamping screw, in order to move the two claws towards one another for connection of two formwork boards, in such a manner that the supporting elements of two formwork boards are held in the desired position. The connecting device is characterized by a pivotable claw, which is formed such that the pivotable claw can be pivoted between a starting position and a final position, particularly about a shaft of the connecting device. This permits particularly simple assembly of the formwork boards to form a formwork and/or disassembly of a formwork.
