Multiboard compatible Knipex Pliers Wrench hooks. 
Versions for David D's Multiconnect connectors OR the official Multipoint Connectors.

Note: These do NOT work with Multipoints Lite connectors. Only the non-Lite connectors will fit.

The XS hook might also work with the 125 size pliers as they look to have similar size/geometry at the jaws. Let me know if it works - I personally do not have one to test. 

The holders should fit the corresponding Cobra wrenches as well, albeit not as snugly.
