I have now finished attaching an anti theft cable to the cat and upstream to the manifold.  I used ordinary 10mm plastic coated bike cable which turns out to be 5mm cable when I removed the plastic coating.  Still, any thicker and it wouldn't have fitted under the clamps.

Plastic coated? Won't that melt and/or be a potential fire risk?

Converters can reach 800C in some cases.

The plastic coating was removed,  but you are correct about high CAT temperature,  they advise not to park
in long dry grass because the hot CAT or exhaust pipe can set fire to it....
Some people will only consider you an expert if they agree with your point of view or advice,  when you give them advice they don't like they consider you an idiot

My apologies to dbjazz, I missed that bit.  :-[

A hot cat will certainly kill patches of grass, I can confirm that! Oops!

As well as the plastic coating the bicycle security cable had aluminium crimped blocks at each end to create 2 small end loops.  I did wonder if the aluminium would survive the exterior cat temperatures.  However on removing most of the plastic coating it was apparent that the crimps had been fitted after i.e. on top of, the plastic coating!  So I burnt off the remaining crimped plastic with a blow torch leaving a very loose alu crimp which easily fell away. 

So if you ever want to steal free your own bicycle just blowtorch the security cable loop crimp.....

Do know if this lock fits a jazz. I found it on line and it said it was not suitable for a car

Hello @dbjazz
I agree with you, the thieves aren't going to bother to check it to see if it is an aftermarket one or not, they are just going to take it. I like your security measure, and was wondering if you could let me know what size M10 Clamps, you used, and what length of cable, as I'm going to do it to my replacement cat, before it gets nicked!

Sure, they were 48mm M10 clamps - these in fact https://www.ebay.co.uk/itm/280727123167

I went for M10 thickness over the standard M8.    48mm was quite tight but fitted OK with cable underneath.  The bolts were a little shorter than I would like - I couldn't double up on the nuts as there wasn't enough thread showing .  That may be a problem with 50mm and M8 clamps as well.

This is the cable I used - OnGuard 10mm x 2.2m https://www.ebay.co.uk/itm/163733461472 though I paid a bit more  from a different seller.  Remember to strip the plastic and the aluminium ferrules. 2.2m was about the right length to double up.

Don't forget 2 nuts on one of the two cat-to-manifold bolts' ends.

Should cost about 10 for everything.

I had my Cat Converter stolen on the weekend. Ended up buying this one https://www.ebay.co.uk/itm/BM-90842H-Catalytic-Converter-Centre-Exhaust-Front-Rear-oxygen-Sensors/153753193222?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m1438.l2649 and paying 60 labour.
I've ordered the cable and clamps which you suggested to secure the new Cat Converter. Thanks for the idea.

I've linked my son to these posts.
Maybe he'll take a look.
His cat was cut from his 2007 Jazz whilst in the Coventry railway car park.
A**holes.

I installed the clamps and cable over the weekend. Used 4 clamps in total and doubled up on the nuts at downstream end.

Now 2 months after fitting the  cable and clamps I have error codes PO131 and PO132 (02 sensor high voltage and O2 sensor low voltage).  On  the diag tool the sensor 1 voltage jumps around from .15V to .85V and sensor 2 from 0 to .85V. (note the EML warning light was off at the time of those readings).  I am assuming the cheap sensors or the cat fitted by the insurance company have failed?  Looks like I will have to take off the clamps and cable!  I suppose maybe the cable  damaged the sensor wiring but I thought I was careful about that.

Your voltages sound normal for a warmed up cat, but it's only a rough test through OBD.

It's odd to get both P0131 and P0132, sounds more like an intermittent wiring issue than a sensor. Check that the pre-cat sensor connector is fully seated, or has not been heat damaged by touching the cable or clamps, etc. Any damage allowing water ingress may give those codes.

Do the codes reset and return, or are they permanent?

Thanks bear in mind when I captured that OBD data the EML was off.  It's still off by the way, total on time was about 4 hours acrosss several engine starts.   Here are all the readings:
