how to get all gameObjects of a joints network?

Hello, I'm writing a "building" app/game where the player constructs certain structures with parts connected together with joints. However, at some point, cloning of a network of these structures is needed. So i need to clone every gameObject in a possible network of joints along with the Joint info. This is not too complicated, i've already set it up, but the problem is: I can know the connected body of a gameObject through its joint property, but i cannot do it the other way round! is there any way i can get the gameobject that keeps the "connected body" if i only know that body itself?

Thank you :)
