I haven't bought any 'biners in a decade or so, but they used to have 
ones where the slot that the pin in the gate engaged with was L shaped. 
  under load, the pin would drop into the L, preventing the gate from 
opening.  Of course, if you took a really hard fall and permanently 
deformed the metal, you couldn't ever open it.  Don't know if they still 
make them.
