Seeking safety rope end connector

My IG pool was built with 2 built-in connectors for a safety rope that connects via a plastic knob connector (see pic). One of the connectors on the safety rope broke. I am trying to find a replacement, but all I keep finding are the metal hook types. Does anyone know where I can locate such a replacement part?

Did you ever find it?  I have the same exact connector and can’t locate it anywhere…

Unfortunately, we were unable to source those anchors from our suppliers.

No I have not. I need to get to my not so local Anthony & Sylvan store to see if they can help
