Sounds like you are talking about the hose that goes to the heater. It has a snap spring clamp on it. You will be able to handle it better if you buy a new hose and cut the old one off.

IT is harmful if left un repaired as it has the capability of melting holes in pistons.. Run the fault codes or check /change the air/ fuel mixture settings and ignition timing of the engine . Most engines run around 10-12 degrees advanced and any more than that will help cause the problem, as the spark occurs too early and the extra pressure built up by the combustion will combust the rest of the mixture in the cylinder.
