Combination locking and radio frequency interference shielding security system for a coaxial cable connector

A combination locking and radio frequency interference shielding security system for a coaxial cable connector of the type having a female coaxial plug and a male coaxial plug on a coaxial cable, said system comprising:

• (a) a sleeve having an open forward end and a partially covered rearward end, said sleeve sideably disposed onto the coaxial cable;
• (b) a head having an internal locking well, said head rotatably affixed to the male coaxial plug so that said well can lockably engage with the female coaxial plug;
• (c) means for retaining said head and the male coaxial plug with said sleeve, when said sleeve is pushed over the male coaxial plug and said head whereby said sleeve is rotatable with respect to the male coaxial plug and said head when the male coaxial plug and said head are so retained within said sleeve;
• and
• (d) means for selectively engaging said head with and disengaging said head from the female coaxial plug when said head and the male coaxial plug are retained within said sleeve.
