I claim the ornamental design for a joint support wrap, as shown and described.
FIG. 1 is a front view of a joint support wrap illustrating my new design;
FIG. 2 is a rear view thereof;
FIG. 3 is a left side elevational view thereof, the right side elevational view is a mirror image of FIG. 3;
FIG. 4 is a front end view thereof, the back end view is a mirror image of FIG. 4;
FIG. 5 is an enlarged front view showing detail of the ornamental aspects of the design; and,
FIG. 6 is an enlarged rear view showing detail of the ornamental aspects of the design.
The broken lines in FIGS. 1 and 2 are for the purpose of illustrating the cut lines of the enlarged views of FIGS. 5 and 6, respectively. Broken lines in the drawings represent portions of the joint support wrap that form no part of the claimed design.
