Trouble connecting water inlet connection to plastic pipe

[Mdali598]

Hi,

I bought a new sink and it has a 1/2" water inlet pipe but d previous pipework for the kitchen sink is very weird and to be honest I'm not sure exactly what connection I need or what what item I need for to make this work.

please could you help me understand what fitting I would need as I want to connect to my old pipes securely and then use the inlet pipe to connect to my new sink.
