Abstract: A wrench socket includes a socket connection portion adapted to receive a lug member. The socket connection portion has a first face and a cavity extending from an interior of the socket connection portion to the first face. This cavity is adapted to engage a lug member. The wrench socket further includes a wrench portion having inner faces which are adapted to engage the periphery of a connector. The inner faces are angularly oriented to each other and disposed along planes substantially perpendicular to the first or second face of the socket connection portion. The inner faces bound an open gripping region such that the inner faces are slidably engagable with the connector along a plane perpendicular to the inner faces. The wrench socket further includes a mid portion connecting the socket connection portion to the wrench portion.
