Removing the collar shroud

[Pisces67]

Hello, firstly is there a shroud which is fitted to this tap?
If there is I'm finding it very difficult to remove. It's a deva monobloc tap.

Read something simiar that a rubber strap wrench may be required, however need to ascertain if the tap has a collar(shroud) as it is very difficult to see a joint. However the material is plastic rather than brass as
It has chipped a little.
Thanks

Agreed. I once had (on loan) a canvas strap wrench that was very very good. If you know of a good one, please do let me know as it is a tool I feel I'm missing. The only ones I've ever seen on sale are the rubber Boa ones, sadly, and I can grip better with my hands than with the one I have!

Just to update, managed to eventually get the cartridge out but the base of the unit remained in the tap. New spares ordered.
