ASY68:-----Not correct, its not an armament pin!! On the A330 the red "remove before flight" streamer and attached pin is used to stop the arming system lever being placed in armed by mistake. The crew remove and stow the pin THEN arm the door.
So after landing they disarm the door THEN place the pin and attached red streamer back in place to ensure it is disarmed and the arming lever cannot be moved by mistake.
I think the A320 would be the same surely??
