PETZL Sirocco broken buckle fix

I’ve had a PETZL Sirocco helmet for a year and I like it a lot. But my buckle just broke during my yearly Christmas trip to Joshua Tree. Before the Sirocco I had been wearing a 1993 Joe Brown helmet. It blew a rivet, so this Sirocco looked very attractive. It’s super light, and as long as I stuff something inside it (to protect it from crushing), I can pack my pack normally and it survived until last week. The buckle Petzl uses is very fragile. The plastic snap tabs are ultra small. There is a magnet inside the buckle that helps pull it closed. Unfortunately, the magnet also attracts iron ore, of which there is a lot in Jtree. I was constantly having to scrape and blow out the sand stuck to the magnet before it would snap.

Finally, up on the “Heart of Darkness” route, one side of the buckle broke completely. I had to borrow a helmet that day. When I got back to camp I replaced the buckle with one I bought at the jtree climbing store. To get the old buckles off, I shaved down the plastic with a razor knife until I could slide the nylon out of the old buckles. Then I prusiked on the new buckle, extended the strap with some tubular nylon using a water knot and had a helmet again. The repair job is stronger than the original. Here are the photos:
