The ornamental design for a buckleassembly for handbag, as shown and described.
FIG. 1 is a front perspective view of a buckle assembly for handbag showing my new design;
FIG. 2 is a front view thereof;
FIG. 3 is a rear view thereof;
FIG. 4 is a left side view, with the right side view being a mirror image thereof; and,
FIG. 5 is a top view.
The broken line showing of the handles, portions of the handbag, buckle holes, grommets, buckles, and central closure mechanism is for illustrative purposes only and forms no part of the claimed design.
The stippling is meant to indicate a textured surface (such as fabric or leather), while the linear shading is meant to indicate a relatively smooth surface (such as metal).
