If you take a screen top and press it down on your hand and pull your hand out from under it. It will not damage your hand.

What would likely happen is that the ball would lift up the cover and force it's head out. If it got stuck it would pull its self back into the tank, perhaps getting it's neck pinned and stuck from the pressure of the clips, but the cover would not gouge through several layers of the derma. There are several layers that need to be damaged for the scar to appear white instead of black.
