Instead of removing the "lock" of the ribbon cables, one can probably also just pull the plastic part of the socket from the adapter PCB turn it 180 deg and push it back on. This way, there is no danger later on to connect the ribbon cable the wrong way, if ever you need to disconnect and reconnect it. To pull the plastic housing off, I use a knife to go between the PCB and the housing.
BTW this is what I did with my Sanguinololu adapter, which also came with the connectors turned in the (for me wrong) "SainSmart" orientation.
