Upon insertion of the anti-crush ring into the hollow article, the at least one expansion hoop is compressed and deformed to urge the wall structure of the anti-crush ring against an inner surface of the hollow article. Also provided is a method of reinforcing the inlet or outlet of a hollow article.
