One more time people:
8s(silver), 9s(gold) SRAM PowerLINKS - removable with fingers
10s(black) SRAM PowerLOCKS - snap together and require a tool to take them apart.

Also KMC has used at least 3 different designs of master links. The one shipping with the 10s chains is the same design as the Superlink & SRAM 8s & 9s links, and is easily removable/reuseable.
