A clip includes a pair of end portions each having an arcuate portion. A pair of opposed gripping portions are each connected at each end to the pair of end portions. The arcuate portions provide a resilient force on the gripping portions toward one another. The end portions and gripping portions are integrally molded as a single piece of plastic. Optionally, the clip can be used with a base. The base includes a body portion and a pair of opposed raised portions. The gripping portions of the clip snap fit into the base, between the raised portions. This secures the clip to the base and retains the gripping portions in a closed position.
