We claim the ornamental design for a divider, as shown and described.
FIG. 1 is a frontal perspective view of a divider in accordance with my new design;
FIG. 2 is a front elevational view of the divider of FIG. 1 showing the design, the opposite side being a mirror image thereof;
FIG. 3 is a top plan view of the divider of FIG. 1 showing the design;
FIG. 4 is an elevational view of a side of the divider of FIG. 1 showing the design, the opposite side being a mirror image thereof; and,
FIG. 5 is a bottom plan view of the divider of FIG. 1 showing the design.
The divider is illustrated with a symbolic break in its length. The appearance of the article at the center between the break lines forms no part of the claimed design.
