The molding on the outside shouldn't be opening up when you are hooked up. From your description, it would appear as though there is some separation taking place which shouldn't be happening.
How much are separation are we talking about? When you say the "outside opens up a little", can you be a bit more specific? Exactly where is this gap other than on "the outside"?
If you are able, a photo of this "gap" would be helpful to better understand the extent of the problem.
