The tab is provided with a visible indicium which indicates the proper degree of overlap of the ends of the cuff when the latter is affixed to the patient's limb. The cuff may be used by only one patient, and may be discarded when the patient is finished with it. The cuff is provided with a one-piece slip luer fitting which includes a flange disposed within the chamber, and an annular tube projecting through an outer component of the cuff.
