In the 1.2 version (which is on SqueakMap) you can ask any Morph 
(including connectors, of course, since they can be connected to by 
other connectors as well):

connectedMorphs
	"Answer all the morphs I am connected to (empty unless I'm a 
connector)"

connections
	"Answer the NCConnectorMorphs that are tied to me"
incomingConnections
outgoingConnections

and you can ask Connectors:

destinationMorph
	"Answer the morph connected to my first vertex, if any"
sourceMorph
	"Answer the morph connected to my first vertex, if any"

subNet
	"Answer a set of myself plus all of the connectors that are either 
connected directly to me or that I'm connected to (recursively)"

validConnections
	"Answer an Array with all of my valid connections. This will be from 
0 to 2 long."

They're stored in a #connectedConstraints property in the morph's 
extension (indirectly, these are really the ends of the connectors 
but you can query them for their owners and get the connectors).

Well, some ideas I had for an additional scripting interface were:

connectStartTo <aMorph>
connectEndTo <aMorph>
connectTo <aMorph>
disconnect

startConnection
endConnection
