Cross-posting from Neumann's site:
the circular connector on the capsule side is snapped in, so there is a high risk of breaking it, when trying to snap it out.
Thus, attempts of disassembly are only recommended in the case of an actual cable failure.

Was hoping this wasn't the case, but it makes sense and is going to be tough to get them apart. Looking at mine, there is nothing to grip or latch onto from the top side and the contact rings are delicate enough that I wouldn't want to jam anything between them that would be used as a lever for risk of breaking them. Moreover, I would never attempt to try to pry out the platic snap ring by jamming something between it and the colette threads. That is a surefire way to damage the delicate threads as the metal of the threads is extremely thin.
It might be possible to push the snap ring out from the cable entry port, but I can't be sure. I believe there is a small circuit board inside the colette, so you're not pushing the plastic snap ring out directly. I don't think breaking the circuit board would be the end of the world, assuming you can otherwise safely disassemble the colette.
On a positive note, Mr. Schneider did not say that they are glued in. MBHO active cables are designed similarly to the Neumann active cables ala a plastic plastic ring that snaps in place, but they're unfortunately glued in place. From first hand knowledge, trying to disassemble them can easily result in total destruction of all plastic parts and using heat or solvents to break the glue is very risky.
