ABSTRACT:
Described herein are heat recoverable composite couplings comprising an outer, tubular heat-shrinkable sleeve and a hollow insert member adapted to receive plural substrates. The insert member has a tapered surface to allow it to accommodate substrates of different sizes. Recovery of the outer member forces the insert member into secure contact with the substrate forming a union between the substrates.
