The article includes a flat generally rectangular central portion having first and second sets of ears affixed opposite sides of the central portion. The sets of ears include first and second ears bent respectively in upward and downward directions relative to the plane of the central portion wherein each pair of ears located diagonally opposite one another across the central portion are bent in the same direction relative to the plane of the central portion. A third set of ears extend from the central portion and terminate at a substantially rectangular member whose plane of orientation is substantially perpendicular to the central portion. The element further includes a retaining ring affixed to the substantially rectangular member to provide for ease of installation within a suitable conduit.
