A cable-lock device includes a housing, having a length-axis between a distal end for accepting a cable and a proximal end for exiting a cable, including a first bore parallel to the length-axis of the housing and configured to allow passage of the cable, a second bore off-center from and parallel to the first bore including a tappet axially displaceable in the second bore and parallel to the length axis of the housing, and a third bore oblique to the first bore which intersects with the first bore including a locking roller axially displaceable in the third bore with a predetermined angulation to the length-axis of the housing, a resilient structure which exerts a force on the locking roller in the direction of the intersection of the first bore and the third bore, and a fastener unit at the proximal end of the third bore.
