Abstract
Flexible hollow articles comprise an expanded elastomeric inner member and an outer restraining means. The restraining means is made of a notch-sensitive material so that when score lines are made in the restraining means, they can be propagated through the material by distorting the article. The stiffness and elongation of the restraining means, and the peel strength of the bond between the inner member and the restraining means, are so chosen that when suitable score line are made in the restraining means, at least part of the restraining means can be pulled away from the inner member, thus permitting the inner member to recover. The articles are useful for covering substrates, especially splices and terminations in electrical cables.
