Mechanical connectors

It seems that the Rocket/Streichfett/2-pole have indents in the base of the casing which appear to be there to allow one to mechanically join these products to one another.

However I cannot remember seeing any little mechanical links suitable for this in the shipping box. Does one have to order these separately?

I never saw or heard about such connector made or distributed by Waldorf

I would love to connect my Rocket and Streichfetts mechanically.
