OK, so after trying with some force I just could NOT get these on.
The process also caused some flexing and weakening of the plastic lugs on the back as they were bent out in the wrong direction.
Eventually after some careful study I worked out why, it was the metal spring ring causing the problem.
Without it they did clip in, but rather loosely, and not entirely flush at the edge. With it, no chance!
The ring is basically too large and too strong and has only a small gap so cannot shrink enough to clip on.
As it happens I have some redundant centres I bought a while ago that fit nothing I have. They too use a similar ring so I compared.
Superficially the same size, but the spare ones use a thinner, more flexible, wire and VERY IMPORTANTLY have a larger gap (extra 5mm or so) so can be compressed more.
So I just swapped the rings over between the new centres and old spares and they now fit quite well and look OK.
The only real problem is that one has damaged/flexed lugs that could break off at any time.
I guess they may also have worked OK if I cut a bit off the ring to make the gap larger, but swapping was easier and they seem fairly secure with the slightly weaker spring.
