ABSTRACT:
A clamping device which has clamping units including a pair of openable arms extending in a V-shape toward one side of a pivotal center and in a X-shape toward both sides thereof, and a pair of retainers projecting from the ends of each of the arms a predetermined length toward the end, and a clamping means slidably engaged with parts of the arms of said clamping units for adjusting and holding the amount of closing of the arms in response to the thickness of an article to be clamped. The article is clamped and held by the force of restoration produced by the deformation of the clamping units occurring when the article is inserted between the pair of retainers and the pair of arms are closed.
