How to connect this black pipe?

[JohnMalcolm]

Hi All,
These push fit type pipes are in the bathroom, they twist but I was not able to disconnect the long 35mm black one - quite tight fit.
Is there any compression type connector or flexible connector I can use to connect these two pieces or any transition to 40mm system?

I have cut it to be able to raise the trap and connect to the new basin which turns out to be higher than the old one.

Is this what I am looking for?
Coupler 32x32mm
The transition?
32 to 40mm connector
For some reason it does not allow me to post links in here.
Please advise.

Bit of 32mm push fit pipe and remove each stub of pipe pull and twist will move
