ABSTRACT:
A device is presented for coupling either a coaxial cable to a coaxial plug or two coaxial cables to one another, requiring a presetting, or activation operation to occur prior to making the coupling or the device will not permit electrical coupling to occur. Also, once the coaxial cable coupling to the device is removed, the device is inactivated so that the electrical connection cannot be made again unless a new presetting operation is performed.
