Abstract: The new advertising band for quick and easy locking, unlocking and re-locking about merchandise is a flexible strip having a lead end section, a body section, and a tail end section. The lead end section is equipped with a lock aperture having a maximum dimension in the longitudinal direction and a minimum dimension transverse thereto. The body section has a substantial length and transverse width for displaying advertising information. Its length is at least as great as the combined length of both the lead and the tail end sections. The tail end section has laterally paired locking members separated by neck members along its length. It is easily pulled through the aperture to lock any pair of the locking members against the minimum dimension edges of the aperture and yet is easily and quickly unlocked from the aperture by aligning its locking members with the maximum dimension of the aperture and pulling it free from the aperture. The ideal lock aperture has a Saturn design.
