Super light lock recomendations for ride to Morocco

When compared to london anywhere seems alright, but I think theft in urban parts of france is really bad. Apparantly if you park a car with the parcel shelf in place it WILL be smashed into. You have to show your boot is empty and you have no car stereo or the thieves will get in there. European capitals, rome & paris etc are full of pick pockets too. I dont know about bikes, but its got to be pretty bad too. Not out in the country though of course, but neither would it be in the UK.

admittedly the only cities I spend the most time in France are Montpellier and Paris, but I always see decent bike being locked with those £5 cheap chain lock that have a colourful transpance cover on them, more than often seen cyclists leaving their bike outside a shop for 20 minutes before returning to their bike.

base on that, it does seemed like France is pretty good when it come to bike theft, perhaps the French are quite strict when it come to bike theft? I don't know.
