10 Pcs Zipper Locks for Backpacks, Zipper Lock Clips, Anti-Theft Deterrent Detachable Zipper Connectors, Double-Sided Small S-Hooks Zippers Pull Clips for Traveling and Camping

These are very useful for all sorts of things. They can be used as keyrings, holders and clips to hold zips together. They're not lockable, but the spring clips are quite strong, so things shouldn't come out easily. For keeping zips together, they're a minor theft deterrent, but if it means the would-be thief moves on to the next bag, they've paid their way. They take up no space, so it's well worth having a few of these on your travels, just in case.

These little clips are extremely useful for fastening bags and keeping them secure. They are small and discreet and come in 5 different colours. Although it's not a lock just this simple clip would be enough to deter opportunistic hands.
