Gosh! This thread is a blast from the past. Just wanted to add as a few years have passed since my last post that you live and learn. Hanging the lock off the turnlock closure is definitely not a good idea as BBL stated above. It leaves a smiley mark on the leather and bangs around too much. I have also used Perlerare's method above but I ended up with permanent kinks in the clochette which are a pain to straighten out. I now just leave the lock in the little fabric bag, untill someone comes up with a better method.
Hi Syma

I agree, I used to tie the lock and clochette around the handle (in fact my SA put it on like this when I bought several of my bags), but now they are both kept in the box at home. The lock can leave a smiley mark on the leather, the clochette can get kinked and the clochette has left silvery marks in an arc shape on my bags (including Togo) as it swings backwards and forwards when the bag is used. Better for me to not bother!
