Eberspächer dash to 60mm vent hose adapter

From my built of a campervan Landrover, I installed a second airheater the Eberspächer Airtronic D2. To get the hot air directed to other than under the seat, this adaptor just connects to the usual boardmount to 60mm hose. The thread on the tube just fits the windings on the hose, no clamp needed.
