ABSTRACT:
An improved tong-type clamp is described which includes a cam pivotally attached to one of the clamping members. The cam is detachable so that the cam can be removed. Then the clamp can be opened to any desired extent (e.g., to allow the clamping jaw to be extended around an enlarged portion of an object to be clamped), after which the cam can be attached to the clamping member again.
