Device for connecting electrical conductors

A device for electrically connecting at least one conductor (54) to at least one other conductor comprises a dimensionally heat-stable polymeric layer (48) having at least one window (56) therein and a quantity of fusible electrically conductive material (58), e.g. solder disposed with respect to the window or windows (56) to allow it to flow through the window and to form a conductive connection between conductors positioned on opposite sides of the polymeric layer. The device includes one or more hollow positioning elements, which are preferably formed as pockets (52) between the heat-stable layer (48) and a further polymeric layer (50). The positioning elements are used to retain conductors (54) in position in the device before and during formation of the connection.
