Think I may have one in shed but the pins can be fixed.
Went and broke one of mine about a week after I had it.
If you have a pop riveter its dead easy to make it better than new.
Drill 3.2 mm hole where pin should be, insert rivet with a small washer either side of plastic, use rivet tool to squash rivet but only to point where it grips plastic (not til stem snaps off as usual). Cut stem off a suitable length, drill & glue broken peg onto rivet - assuming you have broken bit, or use something similar.
Got one in shed but same problem as your current one. Can repair it as outlined above if you're interested.
Pop rivet, washers and a bit of plastic rod pressed into service.
Bit of paint added (though you can't see it when all back together.
