ABSTRACT:
A sleeve for clamping and connecting items to be clamped or connected includes a plurality of windings of heat shrinkable material bound into a sleeve which is placed over the item to be clamped or items to be connected. The heat shrinkable material in the sleeve is secured in such a way that upon application of heat to the sleeve, the heat shrinkable windings will shrink and exert inward compressive pressure about the inner surface of the sleeve and thereby about the item to be clamped or the items to be connected. When desired for clamping a tubular item, the clamp can be incorporated as part of the tubualr item by incorporating the windings of heat shrinkable material into the end of the tubular item. The method of clamping of the invention includes the steps of positioning a tubular item over the item to which it is to be clamped and then placing a pluraltiy of windings of a heat shrinkable material about the tubular item where it surrounds the item to which it is to be clamped. Heat is then appllied to the windings to cause them to shrink and put clamping pressure about the tubular item.
