  • Patent number: 5457857
    Abstract: A clamp, for example of the conventional "clothes peg" type, is provided with a wedging device 9 which may be selectively locatable between the rear ends of the two clamping members 2 so as to urge the rear ends apart, and thereby by virtue of the pivotal connection 4 between the clamping members 2 to urge the clamping jaws 3 together.
