Abstract
Abstract A pair of parallel clamping arms hold an adjustable loop, which when applied to the limb, provides a device for puckering the flesh for injections. The parallel clamping arms extend from a pair of bent arms which have a spring attached thereto at the lower portion thereof. The spring serves to push the clamping arms inwardly and to maintain the clamping arms in a normally pressed together condition. The adjustable loop is formed of two cooperating interlocking strips which overlap one another. The loop is adjustable by varying the degree of overlap of the two strips.
