Physics Constraint strength

There’s a way to raise the strength of a physics constraint? I’ve a BP with a physics constraint who keep 2 rings together but if a force is applied on them the rings splits and I don’t want to.

Thank you in advance

EDIT: the constraint are dynamically created so I don’t know how to set the Linear and Angular Breakable properties.

I am curious about this. I can’t find where to set those properties. I’d like to be able to dynamically enable “Linear Breakable” after my actor comes to rest initially.
