How to unclip ISO terminal from connector?

Hey

My aunt asked me to fix her car radio in her second hand car.

The previous owner actually messed up the memory cable in the ISO connector

how would you remove those clips

I tried without success with a small screwdriver.

I tried to buy a very small pair of pliers.. but can't find one small enough.

I think the plastic block comes apart.
