Stumped: Toyota CV boot clamp

[TwoC400s]

Bottom line: I received a Toyota branded CV boot kit today and it had a style of CV boot clamp I had never seen, and can't find anything about it on the internet.

Back story: While doing the front breaks on my daughter's 2008 Prius last week, I noticed the passenger side boot had split. So I googled around, found a couple of decent tutorials (Shout out to Car Care Nut on YT), and figured I'd jump in.

I was expecting one set of Oetiker style cv clamps (usually outer boot) and one set of of foldover band clamps for the inner.

What I got was a set of foldover clamps (expected) and another *different* style of clamp that looks like a foldover clamp (it has a tail and the two side tabs to tap down, but it also has a locking mechanism... I can't anything like it on the google machine.

Is there a tool for these so I don't screw it up?

They look identical to me. Both seem to have the locking mechanism you mention.

Yes, this is one set for one end. The other end has the normal Toyota fold over style.

I suppose I missed something in your original post. Never having owned a FWD Toyota, I can't help much. Are you afraid that they won't lock when you fold them over?

Yeah, I'm just worried when I fold them over there's some secret handshake (so to speak) to get them to lock in before I fold the tabs over

There's a number on the old clamp signifying the length. Have you matched that number with one of the new clamps in the kit? And then that style on the new one doesn't match the old style? There will be more clamps than you need in the kit to fit other applications.

I was planning on removing the axle tomorrow. I haven't gotten under the car to see what each band length is. It came with a few extra smaller clamps, but only two of the larger clamps, so I will have to use the larger clamp in the picture at a minumum. I'm assuming it's the inner clamp, but will confirm before I cut the old one.

My main question is how this hybrid (for lack of a better word) clamping mechanism works. I've used Oetiker style clamps many times, and I've seen tension / fold over clamps before as well, but I've never seen a foldover clamp with a retention mechanism like this.

I don't understand.. you can't just fold the long tab over center and then fold the shirt little tabs to retain it? Folding it over center should make it so that there is little to no for e required to retain it with the short tabs.

Initially that's what I thought as well, but the more I look at it the more confused I get. It has *two* sets of tabs, the tall ones like you would normally just fold over and tap down with a hammer, and a second smaller set that almost looks like guides. And the tail has some kind of hump that looks like it should lock into the smaller hump that's just past the tall tabs.

Just doesn't look like anything I've ever seen before.

Can you get a pic of the clamp in question?

it's two clamps up above, here's a close up of the locking mechanism.

I'm assuming I fold the blue side back towards red, and the small hump past the tall tabs (red side) locks into place in the cutout of the blue "tail".
