Abstract: A method of making an electrical connection between two electrical conductors includes, in addition to making the electrical connection, the steps of positioning the conductors within a heat-shrinkable sleeve whereby they are held, by an insert positioned within the sleeve, in a substantially fixed transverse relationship to each other in the sleeve, and applying heat to shrink the sleeve. Electrical connectors are also described, one of which comprises a heat-shrinkable sleeve having an insert positioned therein for holding conductors to be connected in a substantially fixed relationship to each other, and a quantity of solder positioned within the sleeve between the insert and an end of the sleeve. A further connector comprises a heat-shrinkable sleeve having an insert positioned therein, the insert comprising at least two compartments side-by-side to one another.
