Found in this thread (Page 2) something about removing the nipple and went for it.

It came out very easily.
But not as it should be! Hardly used force or pressure.

What now?
I found out that this is not a Morgan part and couldn't find a replacement.
A new radiator? Maybe,
But; I'm an old-school engineer “why replace it if it can be repaired"

let's go for it.
First find the right O-ring. The number of different sizes is infinite. Had to do 2 shops for the right one.

Put it back in and it fit perfectly. But now he has to stay in place.
My first thought was to stick something between the top bracket and the nipple.
But because they can move in relation to each other, not a good idea. Then I saw the mounting screw behind the nipple!
Made a bracket (squared?) that presses on the nipple.

After a tip from Gambalunga and rereading this thread, I thought this would be a good tip for someone with the same problem.
Peter has the same problem with the radiator.
He went looking for this part (that I couldn't find) and found the answer in Ukraine of all places.
Apparently it is also used by BMW and Mercedes.

Here's what Peter found.

I have noticed some fogging of the antifreeze on the top of the radiator, where the air bleed hose comes to the return connector. Was observed only when cold. Seems like the o-ring has dried out and is leaking slightly when the car is cold.
Trying to gently pull it out to replace the ring I eventually broke one of the three anchors, and then I got a surprise. BMW is like that, it doesn't come as an individual part, you have to buy the radiator assembly...
Good thing other manufacturers are smarter, and I found some info on the internet that this part is perfect for a Mercedes. I decided to use it because it can be delivered the next day.

You can clearly see how the O-ring is shrunken

The only problem is that they charge more for the delivery than what the piece costs.
As there is a MB dealer in the neighboring town, I went there to ask about this article no..
They didn't have it in stock but I could pick it up the next day for 10€ ex Vat.
ordered two "for the some price as one delivered" to have a spare or to help someone in need.
