Actually it's not that complicated. 

import maya as cmds

connectionList = cmds.listConnections('QUERYNODE' , source = True , destination = True , Plugs = True )

or if you want to query an attribute directly :

import maya as cmds

connectionList = cmds.listConnections('QUERYNODE.ATTR' , source = True , destination = True , Plugs = True )

legend :

if source = True : 
Give the attributes/objects that are on the "source" side of connection to the given object

if destination = True :  
Give the attributes/objects that are on the "destination" side of connection to the given object

if plugs = True :
If true, return the connected attribute names; if false, return the connected object names only
