Your stock plastic receptacles get worn over time, especially on lowered subframes. These will still wear, but at a much slower rate. When the stock receptacle gets worn out it allows the seat to move back enough for it to undo the latch.

These should work with all subframes, but you may not be able to use the pin clips with all subframes or tail light configurations.
