<p>Astract of the Disclosure An article which comprises a hollow, radially recoverable member having at least one open end and held in a radially extended condition by a second member outside the recoverable member, by means of a bond between the outer surface of the recoverable member and the inner surface of the second member. In a preferred article, both members are sleeves. The bond is capable of being sufficiently weakened by the application of solvent thereto to allow the recoverable member to pull away from the second member and shrink radially. The second member preferably has apertures to allow radial access of the solvent to the bond and, moreover, is preferably frangible. It may comprise a plastics or metallic material having weakened portions to enable it to be removed from about the recoverable member after the latter has pulled away. The article is useful for protecting other articles and, may, when it is of an electrical insulating material, act as an insulator.</p> |
