Basically, there are 2 stubs that are fixed to the firewall in the engine bay, these are what the factory quick-connect fittings clip onto. However, they have enough length and a rolled lip on the end that allows you to just slip a normal rubber or silicone hose over the end and fix a clamp, just like any of the other coolant hoses. I don't have any pictures on hand at work, but I can try get you something when I am at home.
Here's a picture from google, once you slip those quick-release fittings off. The silver stubs are sufficient to attach the new pipes onto.
When I did my car I ordered the full coolant pipe kit from Roose Motorsport and did everything in the engine bay. I am not sure if they sell the pipes individually, but you might be able to email them and ask.
