Where can I get a canon style speedlite connector

[ditonics]

I am making up some external battery packs for my speedlites and didn't want to do the usual thing of cutting in a 3.5mm jack.
My speedlites all have the canon style HV external battery connector, Yongnuo use the same external battery connector but I cannot find them anywhere.

Any help really appreciated.

Godox do canon power cables for their power packs. Cheap and readily available. When it came to it, I just picked up a godox power pack and cable myself.
