Broken exhaust clamp

[rocket]

Gents, found that one of my exhaust clamps has broken today. I won't be able to fit a new one until next weekend....in the meantime do you think I should avoid using the car? It's the bit shown in the pics below. There doesn't seem to be any movement between the 2 sections of exhaust without the clamp, but don't want to take any unnecessary risks. Wadya think....cheers?!

Cheers folks, makes sense not to use it until its fixed.
Hi Ian, many thanks but I've already bought a replacement clamp off fleabay today. Didn't see you in Tesco today...we were a bit later that usual.
