Query: can't hold onto power plugs

I was looking for a car Y adapter for the cig lighter so I could hook up a radar detector and a GPS unit. This seemed to fit the bill, however the adapter doesn't hold the plugs too well and both small and large plugs would pop out of the adapter. Sometimes plugs would pop out of the adapter from the car hitting bumps in the road or whatever and it would disconnect devices. All in all, not exactly what I was looking for as it could not get a secure grip on the power cables plugged into it.
