A clamp assembly includes a first clamp half-piece and a second clamp half-piece. In one example, the clamp half-pieces are identically shaped. In one example, each of the clamp half-pieces has at least one integral pin and at least one aperture. The first and second clamp half-pieces are pivotally connected to each other via a first snap-fit interface in which the integral pin of the first clamp half-piece snap-fits into the at least one aperture of the second clamp half-piece. The clamp assembly can also include a link arm connected to the first clamp half-piece via a second snap-fit interface. A lever arm can also be included that is pivotally connected to the link arm via a third snap-fit interface. The clamp assembly does not require separate link pins or other parts and only includes four components: the clamp half-pieces, the link arm, and the lever arm.
