interactiveCloth and attached colliders

I have an interactiveCloth with several attached colliders on it.

But sometimes, even if the colliders are on my cloth, the cloth is not attached to them, and even if the attachements are not tearable, well…the colliders can be easily detached from the cloth (even with an attachement tear of 10000).

I am doing something wrong ?

Is there any chance you could post a screenshot showing how the colliders and cloth are arranged? It’s difficult to know what could be going wrong just from the description.
