safety lock
Prevents accidental opening
A safety lock is a mechanism that prevents accidental discharge or operation—most commonly on firearms, where it blocks the trigger or firing mechanism until deliberately released.
The term extends to locks on medicine cabinets, car doors, or equipment designed to prevent access by children or unauthorized users: Make sure the safety lock is engaged before storing the gun.
