Jet eyeball ring removal pool

[PhinsFan]

I believe there's a tool out there that could assist me in getting the "ring" off of this eyeball jet. (see pic). Each time I try to use either channel locks or pliers -- a piece of the plastic breaks off. I saw a video online where someone removed one of these with a simple tool - I think they referred to as the "blue tool". However, since that's not the real name -- I don't know where to find it or what to search for. Please let me know if anyone has some thoughts! Thank you.

There is a special tool from Hayward, but I just use a steel putty knife...

If there is slots inside that fitting, this is the tool:
