If someone is determined to break into my luggage, they will - and they'll probably have suitable tools to hand to cut off a lock. However, this Master Lock padlock should dissuade the casual thief which is why I bought it. It is the perfect size to thread through the zip on my suitcase. I looked at several brands on Amazon, but I already have many Master Lock padlocks that I have had for several years (locking my shed, boats, etc) and I am very happy with the brand. It is very easy to set the combination (that is, the instructions were simple to follow).

I bought this since my daughter kept getting stuff swiped at school. It's more than enough security for her but is easy enough for her to use. She is 6, I expect a 5-year old could operate it without difficulty after a little bit of practice. It does fit through the holes on the zipper pulls of her backpack; I expect it would fit most backpacks. It's attractive enough and small enough to hide in the side pocket when in use, and doesn't cost an arm and a leg. The "hasp" is flexible cable, so it will not hang on a hook when it is open, and my daughter did lose one somehow. The lock can be re-clipped to the backpack without actually locking it, which is good and bad, It's good in that it's easy to re-clip / unclip while packing the bag, and can be re-clipped to keep it from getting lost. It's bad since it can be re-clipped and can be mistaken for being locked, but it's not - you need to rotate the combination wheels after clipping to lock it. Note this is no different than a lock on a briefcase or any other similar lock. As others have no doubt noted this is about the lightest duty lock you can get, and is barely more secure than a nylon zip tie. But if that's what you need, this will do the trick. I imagine it would be a convenient way to get a little peace of mind with checked luggage.
