    Abstract: A wedge-type cable clamp has an outer member providing an open-ended tapered recess receiving a wedge around which a cable is wrapped in the usual manner. The wedge projects beyond the larger end of the recess, and the sides of the outer member extend past the wedge to shield it against random accidental forces. A cut-out in the sides provides finger access for intentionally releasing the clamp.
