A plastic safety closure with a tamper-indicating band is described. The closure includes a tamper-indicating band depending from the skirt of the closure. The tamper indicating band includes a frangible portion with one or more openings therein. The openings may form an interrupted slot or a continuous slot. Each opening includes a lip projecting outwardly therefrom and another lip projecting inwardly therefrom. These lips provide greater contacting area at the inner surface of the opening, thereby facilitating the alignment of the lower portion of the tamper-indicating band as it is forced into position on a container fitment.
