ABSTRACT:
A beading for baggage includes an elongate flexible tubular portion with legs or flanges projecting therefrom. A band spring is rotatably positioned in the tubular portion and dimensioned so that the spring is relatively flexible in one direction and relatively inflexible in another direction. The spring urges the tubular portion into a sharply defined shape. The band spring can rotate when the tubular portion is deformed in the inflexible direction of the band spring and can rotate back to restore the tubular portion to its sharply defined shape.
