Abstract: A one piece plastic clamp has a generally U-shaped outer structure including two outside legs and a thinned and downwardly curved upper bridging region from which the legs integrally depend. The clamp further includes a live hinge toggle joint for spanning the upper outside ends of the legs. The toggle joint has a release position peaking freely above the upper bridging region as the legs move relatively together and apart in the release position, and has a stable snap lock position directly adjacent to the upper bridging region thereby forcing the outer legs together in a clamped position. Two oppositely facing inner clamping jaws are relatively moveable freely with respect to each other and with respect to the outer structure in the release position. The jaws are for clamping an article between opposite faces when the clamp is in its snap lock position.
