Abstract: The invention provides an electrical housing having a cover portion 14, and a base portion (not shown) defining recesses for receiving electrical connectors 24. Each connector has a casing 26 defining a nozzle portion 28 through which terminations of electrical conductors 30 are receivable into the casing 26. The casing 26 holds captive a displaceable element 34 resembling a cylindrical plunger. The element 34 co-operates with a metal blade located within the casing 26 to strip off the insulation of the conductors 30 and join them electrically when the element 34 is urged into the casing. In use, a tool formation 40 forming part of the cover portion 14 is positioned over the displaceable element 34. When a downward force is applied to the cover portion 14 the tool portion 40 effectively urges the element 26 into its final position, thereby joining the conductors 30 electrically to each other.
