Abstract
A lock assembly is formed from a two-piece plastic unit that is held together and to the compartment door by a planar lanced metal spring. The latch projection is ramped relative to the latch retainer slot within the compartment door to cause the latch piece to become jammed within the retainer slot in the event the door is subjected to severe internally-generated gas pressures.
