Tim+ was thinking very hard :
I think it is just a "standard" Hoselock type connector. They're made by
many people these days though and there will be small differences in
"non-critical" dimensions.

I have several of the usual size, one which is bigger and almost
tightens.

Is it possible it is some American thread. I thought Europe tended to
use BSP, or possibly some metric thread. TPI or pitch and overall
diameter may narrow it down and can be put in google often with at least
some hits. Try the metric and Imperial version of the measurements. The
major diameter will be different from the measured diameter so judicious
guessing helps.





Why not buy a brass one? Unlikely to break again and probably has a larger
internal bore.

I have a brass Hozelock version which has a too small internal thread.
