I claim the ornamental design for a one-piece clip, as shown and described.
FIG. 1 of the drawings is a perspective view showing the front side, the top, and a first side of a one-piece clip embodying the design of my invention;
FIG. 2 is an elevation view of the back side of the one-piece clip;
FIG. 3 is an elevation view of a second side of the one-piece clip;
FIG. 4 is a top view of the one-piece clip; and
FIG. 5 is a bottom view of the one-piece clip; and,
FIG. 6 is a reduced-in-scale environmental view of the one-piece clip, showing it holding a previously opened snack bag in a closed configuration.
The portions shown in broken lines in FIG. 6 are for illustrative purposes only and form no part of the claimed design.
The one-piece clip is a clamp device for retaining a snack bag and other bags in a closed configuration after opening.
