An electrical connector including two tube sections which are open at a first end of the connector; and a connecting section connecting the two tube sections to each other. The tube sections and the connecting section form a conductor receiving area which is open at the first end of the connector. The tube sections are adapted to be expanded towards each other to capture the conductor. An electrical connector attachment tool is provided for the connector which includes a stationary section and a movable section which can exert a compressive force to an electrical connector positioned between the movable section and the stationary section. At least one of the stationary section and movable section includes a connector wedge. The connector wedge includes two wedge shaped projections extending in a same direction and a conductor guiding channel between the two wedge shaped projections.
