Abstract
An integral and inexpensive tying or bundling clamp device is disclosed, together with the method of applying the same. The clamp comprises a metal band having at one end an anchor defined by a series of convolutions of the band wrapped to provide a passage for the free end of the band. The device is applied by encircling an article and passing the free end through the passage and tightening the band while applying a reacting pressure against the convolutions, whereby the same are caused to constrict and frictionally to retain the band in the anchor.
