ABSTRACT:
A flattened resilient sheet metal band prestressed to assume the shape of an extended tubular rod when unstressed, is stored as a coil wound on a spool. The end of the band is fixed to a post. When the coil is released, the band assumes its tubular shape and the end of the band fixed to the post encircles the post. A clamp responsive to the change in shape of end of the band clamps it to the post when the band assumes its tubular rod shape.
