We claim the ornamental design for a jump rope handle, as shown and described.
FIG. 1 is a perspective view of a jump rope handle;
FIG. 2 is a perspective view thereof;
FIG. 3 is a right side view thereof;
FIG. 4 is a left side view thereof.
FIG. 5 is a back view thereof;
FIG. 6 is a front view thereof;

Furthermore, the singular screw-like element illustrated in each of FIGS. 1-4 and 8 does not form part of the claimed design.
