Abstract

The invention refers to the Belgian Patent No. 820880. The two pipes (16, 17) are placed end to end and a sleeve (15) is slipped over the pipe ends. The sleeve material is such that it can retrieve its original shape when heated. It covers one or more layers of other materials which are serrated to enable a tight grip to be made on the piping. The sleeves are shrunk onto the pipes, so that the sleeve is permanently strained when in position. The V-shaped outer sleeve aides
