ABSTRACT:
A retainer for use with a bobbin having filamentary material wound thereon to prevent unwanted unwinding of the material. The retainer is formed from a strip of elastic material with one end folded back upon an intermediate portion to form a minor loop, and the other end passed around and superposed with the first end to form a major loop. The three superposed layers in the areas of the intermediate portion and immediately adjacent the two ends are permanently secured and an opening therethrough defined by a grommet. The major loop is stretched to pass over the peripheral edge of the bobbin and engage the outer layer of filamentary material with the free end of the latter passing through the opening in the retainer.
