Whats the pipe made of?
If its rubber you can cut off the split end and reconnect it!
This is if you have enough spare hose to play with!
Most camping gas outlets sell the hose fittings that just crimp on!
I prefer jubilee clips myself!
If its split once though i would change the hose!
Just to be safe!
A quick fix is ok but for the price of a new hose its not worth it!
