I claim the ornamental design for a handle, as shown and described.
FIG. 1 is a front perspective view of a handle from above, showing my design;
FIG. 2 is a rear perspective view of the handle from beneath;
FIG. 3 is a right side elevational view of the handle, the left side elevational view being a mirror image;
FIG. 4 is a front elevational view of the handle;
FIG. 5 is a rear elevational view of the handle; and,
FIG. 6 is a top plan view of the handle.
The broken line drawing of the padlock in FIGS. 1-2, and of the bolt, nuts, and washers in FIGS. 1-6, is for illustrative purposes only and forms no part of the claimed design.
