iPhone audio and power cord clamp

This is a ... I don't know, a clamp of sorts that holds the audio (3.5mm) and power plugs for my iPhone. Whenever I get in my car I connect the power and audio and this allows me to do it in one step and a little easier. It might also help with reducing wear on the cables.

Update: it didn't clamp down on the audio plug enough so I added these structures that stick out so there isn't a gap anymore (see pic).

I also modified the hole for the nut so it wouldn't turn.
