A sealing device for an electrical meter includes a positioning ring and a fragile outer ring. The positioning ring is integral with an upper end of a meter socket and includes an oblique circular upper end which inclines outwardly, an outer peripheral wall which has an annular recess therein, and an annular ledge extending radially outwardly from a lower end thereof and having a plurality of spaced-apart apertures therein. The outer ring is L-shape in section and includes first and second annular arms disposed perpendicular to each other. One annular engaging member projects outwardly from an inner wall of the second annular arm which is concentrically disposed around the positioning ring for engaging with the annular recess in the positioning ring. A plurality of spaced-apart lugs extend downwardly from a bottom of the second annular arm for engaging with the apertures in the positioning ring to prevent rotational movement of the outer ring.
