Abstract
Abstract A bundling strap comprising a one-piece strap including an elongated main body portion, a free end portion, and a head portion through which the free end portion is adapted to be inserted to encircle one or more articles. The head portion has an opening therethrough adapted to receive the free end portion of the strap and at least a part of the main body portion. At least that portion of the body portion which is adapted to extend through said opening of the head portion is formed with diametrically opposed teeth. The head has opposed lateral surface portions adjacent the opening adapted to be engaged by the teeth and thereby hold the strap in position. The opening in the head portion is elongated transversely at an angularly spaced relation with respect to the opposed surface portions such that bodily rotation of the part of the body portion of the strap within the head will cause the teeth to disengage from said surface portions of the head so that the strap can be released.
