I discussed open carry with two younger New Haven police officers at the range. They both told me that open carry is not legal in Connecticut. When I explained to them that it IS legal, they said they didn't believe me, and that they were taught at the (state) police academy that open carry is not legal. Accordingly, I think if you intend to open carry in New Haven you should expect to be detained (at best) and most likely arrested. If you are not in a position to defend agsinst an improper arrest, don't risk it.
