Abstract: A battery booster cable clamp includes first and second members each containing an arm and a jaw joined in the nature of pliers with one arm containing an upwardly extending flexible member containing a plurality of teeth engaging a projection on the end of the other arm to achieve a ratchet action, electrically conductive teeth being disposed at each of the jaws whereby bringing the arms together will bring the jaws together to permit clamping the teeth on a battery post or terminal.
