Technical 2018 van rear heater pipework.

[Nicb]

I have to fit a rear heat exchanger in the back of a 2018 x290 ducato panel van.
Fiat have factory provided the pipework shown in the picture. There is a switch on the dashboard which operates an electrovalve which allows some of the engine coolant to flow around this rear circuit when required.
Firstly does anyone recognise the fittings?
I'm loath to dismantle them until I know how I'm going to remake and extend the circuit.
Thanks

I found these extracts but no luck finding secifications or workshop procedure.

They look like quick release fittings similar to those used on fuel lines. I suspect you depress the metal clips on the side of the plastic fittings and pull them from the metal pipes. Having said that, the hose appears to have been secured over flanged ends of the pipe fittings with compression bands, so I'm guessing a similar diameter rubber hose could be fitted to the existing fittings using narrow jubilee clips or similar hose bands.

Thanks I think your right quick release. I've just emailed zero clips.
In an ideal world I'd like to use 90° elbows to extend the coolant circuit.
