VW Beetle 2008 - How do you remove the old plug from the windshield nozzles?

I have a 2008 VW New beetle that seems to have heated wiper nozzles. I cannot get the pluh out frm the socket on the old nozzles to reple them. Is there a catch to this?
Also, it there an easy way to remove the hoze Seems very stiff (I may have pucntured it trying to pull it off.)
I have seen some video where there is a clip, but mine just has the hose straight to the nozzles. I may need to try some heat, but getting a hair dryer to the location is not easy...

Thanks!
