A cable terminal assembly for battery posts includes interfitting inner and outer members provided with cooperating camming surfaces on the lower portions thereof so that when nested and the inner member is axially displaced downwardly, a positive clamping action is achieved about the battery post with a complete shrouding thereof. Openings and passageways within the two members communicate with one or more bores accessible from without the assembly to permit the injection of a suitable fluid substance designed to minimize corrosion following the filling of these openings and passageways with such substance which bathes the battery post and forms a seal or bead beneath the assembly. Tool engaging provisions on both members accommodate the use of wrenches or the like to relatively axially displace the members during attachment and removal of the assembly with a precise axial displacement being accomplished in view of cooperating threads connecting the nested members.
