We claim the ornamental design for a cover for electronic communications device, as shown and described.
FIG. 1 is a front perspective view of a cover for electronic communications device, showing our new design;
FIG. 2 is a front view thereof;
FIG. 3 is a rear view thereof;
FIG. 4 is a left-side view thereof;
FIG. 5 is a right-side view thereof;
FIG. 6 is a top view thereof;
FIG. 7 is a bottom view thereof;
FIG. 8 is an enlarged view of the encircled portion A shown in FIG. 6; and,
FIG. 9 is an enlarged view of the encircled portion B shown in FIG. 7.
In FIGS. 1-2 and 8-9, the broken lines having an alternating long-dash, short-dash configuration represent a boundary of the claimed design. In FIGS. 6-7 and 8-9, the broken lines having a long-dash, short dash, short-dash configuration encircle portions of the claimed design that are shown in enlarged scale in FIGS. 8-9. The broken lines throughout the figures having a uniformly-segmented dash-dash configuration show portions of the cover for electronic communications device that form no part of the claimed design. The broken lines of all three configurations form no part of the claimed design.
