TV cable quick-connects -- I just slide the connectors on and off ... none of this trying to slide the needle in, then turn-turn-turn the screw connector.

I also love the Hose & Faucet Connector. When traveling in freezing weather, this is a life-saver.
If any of you turn the air blue while trying to get your cables un-plugged from adapter cables & receptacles, this is what I use. I cannot muster up the hand strength to separate those things.
