ABSTRACT:
A heat recoverable article comprises a tube of polymeric material and a spring. The spring has a first bent configuration in which it is bent at a specific angle and a second configuration in which it is relatively straight, the spring being held in its first configuration by the tube. When the article is heated the polymeric material of the tube softens thereby permitting the spring to recover toward its bent configuration. The spring can be selected such that it recovers with sufficient force to bent a substrate over with the tubular recoverable article is positioned.
