SunBay pool robot to 1"1/2 intake adapter / Adaptateur prise balai 1"1/2 pour robot de piscine SunBay

This is an adapter for my pool robot (SunBay 772870) to replace the original junction to the intake (rubber junction, ineffective, and that disconnects when the pump stops).
It makes the junction between the original pressure regulator, which ends up with a conical feature (big diameter 40mm, small diameter 37mm, length 35mm), and the standard 1" 1/2 thread intake of the pool.
Consists of 2 parts:
* the adapter with the 1" 1/2 thread
* a locking ring forced into place on the regualtor cone,
