Pipe fittings type for mixer tap

[mts]

Hello,
I need some advise, will greatly appreciate if someone can help. My mixer tap is leaking from base want to renew it. However the tap cold/hot water feed is connected via connectors/fittings as shown in attached picture. Can anyone please advise how to disconnect tap from these fittings as these don’t tend to have any nut. which can be un-tightened? Any place i can buy these fittings online?

I’ll wager it’s ring with some prongs like all the others!
Can improvise with three little screwdrivers on most types but it’s fiddly- just buy the correct demounting tool if you need to remove them. They are pushfit fittings by the way.
Personally I’d just cut it and replace with something you can get locally.

Marley Equator Demount tool in 15mm seem to be out of stock everwhere 10, 22, 28 are available but of no use.
Some suppliers on Ebay have some stock of new fittings.

This is what they look like.
They also seem to be sold in packs of 10 so are probably easilly broken
