What connection type is this?

[Juman islam]

Hi, I'm looking at upgrading my kitchen sink. The copper piping for both hot and cold have a connection type I've not seen before so does anyone have any idea what they are? Are they push fit couplers which are non-reversible therefore need cutting off? The new tap came with braided flexible pipes which I am looking to fit. TIA

Thanks for such a quick response. So this will have to be cut off right?

It's simpler, quicker, cheaper to cut them off.
Some pushfits are removable with a tool.

Most are put on by a tool too!

From that pic, looks like it's not reversible right?
