ABSTRACT:
A heat-recoverable wrap-around device is made from heat-shrinkable sheet material, two opposed edges of which may be secured together by fasteners so as to form a sleeve prior to recovery. Each edge region is provided with a strip of rigid material lying generally in the plane of the sheet. The strips may be bonded or embedded within the sheet material, or positioned in terminal loops therein, and are preferably so designed that they can be deformed into an interlocking relationship which withstands the recovery forces.
