The application describes an electrical terminal comprising a pair of longitudinally disposed contact members, each having a pair of insulation displacement connectors connectors, one at either end thereof, thereby to link two wire pairs, wherein. each contact member comprises a contact arm each extending in a defined direction, the contact arms leading to a pair of arrestor contacts spaced so as to accept a surge arrestor. The defined direction is preferably substantially transverse to the contact members. This enables the surge arrestor to be placed to one side of the electrical terminal, avoiding interference with ingoing and outgoing wires and avoiding inhibiting access to test points. The contact members are preferably parallel within the electrical terminal. The arrestor contacts are preferably spring contacts, thereby to enable replacement of the arrestor. The contact arms more preferably end at the spring contacts. In a particularly preferred embodiment, the contact arms are non-contiguous with the contact members but are joined thereto. This join can be by way of a lug extending from the edge of one of the two members and engaging within a slot of the other. This provides a particularly simple but effective electrical contact. The lug is preferably on the contact members, thereby placing the slot on the contact arms. This also avoids the need to bend a single-piece blank, thereby risking damage to or distribution of the IDC connector. The terminal will ideally be enclosed within a plastic housing, and this will preferably comprise a recess for receiving the surge arrestor, the arrestor contacts extending into the recess.
