A terminal for a coaxial cable includes an electrically conductive core mounted in a dielectric member. The dielectric member along with the conductive core are positioned within an electrically conductive ground shield. The ground shield includes two identical split-barrel housing members which are joined together. When joined, the housing members form a cylindrical channel having surfaces which intimately contact an exposed length of cable outer conductor layer, creating a conductive connection between the outer conductor layer and the ground shield and structurally maintaining the outer conductor layer concentric to the dielectric sheath and inner conductor of the cable.
