A clamp is provided for fastening to an article that has a fastenable portion of a predetermined shape and size. The clamp body is formed at least in part of superelastic alloy, and has an opening within it slightly smaller than the fastenable portion. The clamp body includes attachment means, which may be in the form of small holes, to which may be applied an external stretching force in a direction and magnitude sufficient to cause the opening to expand elastically to receive the fastenable portion of the article. As the stretching force is released, the opening elastically contracts toward its initial size to clamp upon the fastenable portion. Disclosed also is an instrument attachable to the clamp body for imparting the stretching force to the body. |
