When you drop it, it reconnects or disconnects depending on where you dropped 
it. This is how you reconnect Connectors and move labels.

Sure. Just make it locked so it can't respond to user input.

The connector end morphs don't respond to user input; all of the user input is 
grabbed by the connector. Which responds to clicks near its ends as requests 
to grab the end, so it disconnects the end and attaches it to the hand so you 
can drop it elsewhere.

So are you trying to replace the connector ends or are you trying to do 
something else with the NCConstraintMorph? It sounds like you don't really 
want them grabbable.
