An electrical ferrule for an electrical cable comprises a body defining a circumferential center portion connecting a first flank and a second flank, the first and second flanks arranged opposite one another in a radial direction of the ferrule. At least one latch or lock is defined on at least one of the flanks for selectively fixing the flanks together and closing the ferrule in a manner in which a diameter of the ferrule may be varied during its installation onto an electrical cable.
