Here's a close-up of the standard latch link or duck bill-style of harness buckle. As you can see, the shoulder belts and anti-sub strap all slide onto the lapbelt first; then the lapbelt's buckle is slid through the buckle loop, and the latch is pushed down to hook the buckle and secure the whole setup. It looks complicated, but with use it becomes easy to latch. Note that this style of harness latch is not street legal.
