Kitchen tap question

[Paintfly]

Hi, I had a mixer tap installed a couple of years ago & the circlip at the back at the junction of the spout & mixer tap block wasn’t installed (either didn’t arrive with it or the plumber forgot to insert it). The tap works fine for day to day use, so I only discovered it was missing when I attached a hose & the spout popped out with comic results sending water everywhere lol.
As long as I don’t use full pressure, the hose is useable but not ideal.
I’d like to get it sorted but can’t find the part # or even info on who I bought it from, but I assume it must be a fairly common part as there are many similar designs around.
Any advice on how to source one would be much appreciated. See photos

Just found the make/model: Grohe Ambi monobloc 2 handle mixer tap. They appear to be very commonly available still.
Would I be able to take the spout in to a plumbing supplier & get the necessary? I can see generic kits with o rings are also available. It’s not leaking so only need the retaining clip AFAIK.
