I don't know what the "proper" way to release a connection is, but
"perspective".broker.transport.loseConnection() works for me, where
"perspective" is whatever name you assign to the arg of the "connected"
callback attached to PBClientFactory.login()

Here's a minimal snippet of what I use, cutting out code specific to my

class NetworkClient( pb.Referenceable ):
  def __init__( self ):
      self.remote = None

  def connect( self, ipAddress, port, user, password ):
      factory = pb.PBClientFactory()
      reactor.connectTCP( ipAddress, port, factory )
      defer = factory.login( credentials.UsernamePassword( user, password),
                             client=self )
      defer.addCallbacks( self.connected, self.connectFailled )
      return defer

  def disconnect( self ):

  def connected( self, perspective ):
      print "Connect Succeeded to:", self.remote 
      self.remote = perspective
      self.remote.notifyOnDisconnect( self.disconnected )

    def disconnected( self, perspective ):
        print "Connection Severed"
