An electrical connector comprising at least one metallic tubular sleeve having an open end for receiving an electrical conductor and a closed end, the peripheral inner wall of the sleeve being pretinned; a slug of solder, having a flux associated therewith, hermetically sealed within the sleeve proximate the closed end; a piston positioned between the closed end and the slug and capable of axial motion within the sleeve; means which on application of sufficient heat to raise the temperature of the connector to a first temperature, T1, which is the activation temperature of the flux, breaks the hermetic seal, permits the flux and gaseous products thereof to expand and flow toward the conductor; and pressuring means between the piston and the closed end of the sleeve which, on application of sufficient heat to raise the temperature of the connector to a second temperature, T2, which is higher than the first temperature and which is the melting temperature of the solder, exerts sufficient force on the piston to cause it to move toward the open end of the sleeve and to pressure the slug of solder toward the open end of the sleeve.
