This cannot happen with the current belt - the holster screws into the back of it. And as was mentioned previously, the band that broke does not hold the holster to the belt. The holster clips over the top of the belt and the band keeps it from sliding. I use this system and I would go so far as to say it's a game changer. I carry a 5D2 with a 70-200 2.8 IS on my hip and I've never been so comfortable out in the field. I love it.
I love my Spider holster - so far. 1Ds Mark III (or 7D with grip) with a 100-400, comfortable as hell for a long walk through the woods! And secure, too.
One thing I will mention - initially installing the holster on the belt is very difficult. I spent a good deal of time trying like the dickens to get those two screws, which go through the belt, to line up with the receiving threaded holes on the holster in order to tighten them down. I practiced surgery for 26 years without much difficulty - but this was a tough case!! 
The trick is to squeeze/pinch that holster's retention clip in order to enable the screws to reach their destination and engage, and first you have to "bend" the holster 'paddle' area to see if the screws are aligned properly. Not easy with only two hands.
I think the holster should come pre-attached rather than put the customer through this little mini-hell.
Once done,though, very clever piece of kit as the Brits would put it.
I attached my Spider to the underside of a Really Right Stuff B2 LR II lever clamp so that I can pop it on and off the L-plates of my camera(s). You'll need to get a 3/8"-1/2" adapter to accomodate the hookup.

Hope some of this is useful to you.
