I think all you need is a Mennekes Type 2 cable to J1772 cable. See viewtopic.php?p=489815#p489815
Leafs in the US have a J1772 inlet. We don't have Mennekes Type 2 here. From my reply and response that followed, European ones have J1772 inlet, as well, despite it not being the type found on public EVSE (Electric Vehicle Supply Equipment) aka charging stations.
You should also be able to get EVSEs that are hardwired or whatever plug you use w/a J1772 handle/connector to plug into the Leaf.
