ABSTRACT:
A clamping device for a workpiece, in particular a wheel during a tire changing operation, comprising a supporting base, an upright post wich protrudes through the workpiece e.g. the central hole of a wheel and a securing member e.g. a tube or a plate, which may be non-rotatably positioned on the post. A projection on the member engages with the workpiece e.g. a bolt hole of the wheel, whereby on application of a force tending to rotate the workpiece the engagement of the workpiece with projection and member with post prevents rotation of the workpiece.
