Once it's apart, you'll see how to reverse the process - push both sides of the single link segment in and pull both ends apart.Don
Unfortunately it wasn't the nice two-piece powerlink, it's something like this pic (but with the piece on the right as a complete loop). It locks into place, and is really hard to get off. Probably why they're not as common as the two-piece powerlink.
