No, see these pictures. They started to ship the replacement tubing with the ring.

how do you get that ring? does it come with the replacement tube?

Yes, they come with them.

Check this video by Ecotech on how to replace the tubing, there you can see the retaining ring in action.

I emailed Ecotech inquiring about it. If that is to be used, you would think they would have included it with the most recent batches of pumps. I’ll report back what they say.

I first inquired if the tubing was acceptable for use with highly alkaline solutions and this was the response. No specific answer about the type of plastic used though yet. Polycarbonate I know is not safe with NaOH.

Yes, either an intentional deflection, or someone doesn’t understand the question.
