I've tried that. I don't know which tab to press, if any. Looking at the photo, the bottom three "segments" look like they are a single integrated piece (the last piece has a tiny trap door that opens to expose the wires). The top "segment" (which is a different color), LOOKS like it should separate from the rest of it, but I cannot figure out how to do it. You can see the tab in the "segment" right below it that I've deformed with a tool trying to press it in. HELP!
