ABSTRACT:
A tension clamping device is described, which is particularly suited for use as a bench clamp or vice. A workpiece is gripped in the jaws of the clamping device by forcing a pin, which engages notches in an area depending from one of the jaws, to travel in guiding slots until the workpiece is firmly gripped, then holding the pin in this position by an over-center action of the lever controlling the movement of the pin.
