Abstract: A body is provided constructed of shape retentive but at least slightly bendable and resilient material. The body includes generally parallel elongated side-by-side levers defining pairs of corresponding first and second end portions and a first connecting portion integral with, extending between and connecting one pair of end portions. A second connecting portion of generally C-shaped configuration and including a pair of opposed arm portions and a bight portion connecting one pair of corresponding ends of the arm portions is also provided and the second connecting portion extends between the levers with the free ends of the arm portions formed integrally with the levers and the second connecting portion opening away from the first pair of end portions of the levers and toward the other pair of end portions thereof.
