Query: Doesn't really work for me

I bought this item because I wanted it fit tightly in the power outlet. It does. I wanted to use it to plug in my SIRIUS Satelite Radio. I get no electrical connection to the radio while holding the plug in. When I release the pressure on the plug it pops back out about 1/4". I really wish that I could use this thing. It's a good thing it didn't cost very much.
