Mowing How does this fitting come off the hose?

[Msamt]

This is from a Kioti rear finish mower, remote grease fittings.I have replacement hose but cannot find how this fitting works, any help?
The remote fitting line has been rubbed by a loose belt, crappy design in my opinion...

Squeeze the fitting in where the tube goes in and pull the tubing out. May have to push tubing into fitting while squeezing to get it to release

Thanks! That’s what I was playing with, thought there may have been a ferule under it wasn’t sure how hard to yank on it?
