Anchor 2 movable objects without fixed anchor (inflatable kiddie pool)

Is it possible to anchor a movable object to another movable object in kangaroo?

This is what I’m currently working on:
I’m looking to connect a pressurised pipe together with a cloth (kind of like an inflatable kiddie pool). The final goal will be to give the cloth more elasticity so the pipe slowly starts to crubmle up.

The only problem is to combine the two seperate objects. I can’t use a normal anchor because the pipe and cloth have their own gravity and the pipe also has an expanding notion due to the added pressure.

I’ve tried to use clamplength, coincident but both just act like a fixed anchor (last picture)
