The diaphragms don't mechanically interlock with those on the next car, and, ideally, they just touch under normal operation. There is some room for them to compress during uncoupling, but, of course, no room for a Rix-type uncoupling wand or skewer, and even separating them by using two 0-5-0 switchers can be difficult.
