<{POST_SNAPBACK}>>I know Viessman make them but there could be others
Roco have some in their catalogue. Once you have the part number check out Mackay's website to see if they have them in stock.

The Viessmann ones are 2-pole & based on the Fleishmann Profi-Coupling & can be used as a normal coupling.
The Roco ones are 4-pole & have to be coupled/uncoupled manually.
Both have NEM shanks.
