The utility model relates to a fastening device for formwork, which comprises a tensioner and a clamp. The structure of the tensioner is as follows: a tensioner rod is connected through the stretching pipe, a supporting pipe of the tensioner is set around the outer circumference of the stretching rod, two ends of the stretching pipe are movably connected with the arm handle through a connecting plate, one end of the tensioner rod is connected with a connecting rod mechanism, and the other end is connected. The claw chamber is located in the inner part of the supporting pipe of the tensioner. The claw chamber is equipped with spring and anti-slip three-claw sheet. The front end of the supporting pipe of the tensioner is connected with a steel inlet nozzle. By using the clamp and tensioner together, the steel bar is pulled out. The operation is convenient, fast, time-saving and labor-saving.
