The "Golf ball" styled 
clamp protects cabled devices! It can also anchor your cable to a permanent structure.

CFK27HD Protects all of your computer's cabled devices by attaching them to a steel security cable (the steel cable is available separately or in any Byte Brothers Security Kit). If your equipment has a cable permanently attached, our "Golf ball" clamp can secure it.   For convenience, the cable clamp has a passage small sized cables (e.g. mouse and external speaker cables; medium sized cables (e.g. power cords); and large sized cables (display or scanner cables).  But, regardless of your cable size, it can be secured in this flexible clamp. The clamp is held together with a steel screw and nut. Once the security cable is passed through its passage, the screw cannot be removed, securing your devices. $6.95.

The cable clamp can also be attached to a permanent object and act as an anchor point to the entire security system.
