ABSTRACT:
A spiral, self-terminating coil (12) is formed of an elongated metallic member (10) having at least a first and second tabs (22,23) extending out from a separate one of the ends (18,20) of the member such that each tab is perpendicular to the axis of the member. At least one notch (26) is provided in the member (10) intermediate the tabs and parallel thereto. Each notch (26) is located so that when the member is wound in the spiral, the notches are aligned with the tab inside of the spiral. The inside tab can thus be oriented perpendicular to the spiral turns so as to extend through the notches beyond the spiral.
