Abstract

A latching mechanism for a sub-sea control module is constructed with energy storing means such that a latch is cooked into an unlatched condition by the action of lifting the sub-sea control module to store energy in the energy storing means and is moved into a latched condition by the action of lowering the sub-sea control module into abutment with the mounting base.
