Abstract: A tube of plastic or the like having a flexible bellows middle section and straight section ends with identifying indicia of color or shape thereon to represent information about garments contained on clothing hangers. It may have a flared section and a tapered section on opposing ends of the signal tube; the flared section to fit about the shoulders of a hanger and the tapered section to fit snugly about the neck area. The flared section may have locking nibs to help secure the signal tube to the neck of the hanger. Serrations may extend upwardly from the upper straight section to permit a closer fit to the hanger and help prevent the accidental removal of the signal tube.
