Abstract: A cable locking device consisting of two axially slotted cylindrically shaped closed-end structures, each having attached a rigid tube of smaller diameter than the cylinder. The length of each tube is greater than half the wheelbase of a skateboard, and one tube will fit within the other. The axial slots allow each cylinder to be guided over the trucks of a skateboard, entirely encompassing the truck and associated mounting hardware. Upon installation of the device, the smaller rigid tube has been incorporated within the larger tube. The free end of an attached locking cable is inserted into two aligned apertures, one on each tube, and a locking device contained within the larger tube secures the cable in place.
