is there a Trick to removing the connectors at the harness connector mounting bracket?

Still working on that no start condition on the 26k miles '91 200 TQ 20v car in NH.  I am trying to do a test of the two flywheel sensors...ignition timing sensor and engine rpm speed sensor at the connectors behind the engine, mounted in a stack on a bracket.  The retaining steel spring clips that hold them together seem to be trapped by the immediate connector below...  is there a trick in getting these connectors released without breaking them?  Do you pry the topmost connector out of it's slot first to enable removal of the retaining spring clip?  I don't want to force it and regret it.
