Look in the "*connectors-queries" message protocol of Morph.

In your case, the answer you want would be given by

	myMorph connections

The comment in Morph>>connections says:
 	"Answer the NCConnectorMorphs that are tied to me"

You are correct about this information being in the extension 
(specifically, the property #connectedConstraints), but you should 
never have to look at it there.
