Abstract: This invention relates to heat-shrinkable devices for forming solder connections between electrical conductors. The devices each comprise of a hollow, heat-shrinkable sleeve having first and second ends, and contain a quantity of solder. Both ends contain heat-softenable sealing material which seal the ends upon recovery of the article, the sealing material at the second end being less responsive to heat than the sealing material at the first end.
