Nite Ize Unisex's S-Biner Stainless Steel Slide Lock, Size 4

A really nice little carabiner, Ideal size for your pocket. Well built and sturdy with a built in locking mechanism. Being double ended makes it super convenient for keys etc.

Brilliant clips with locks to ensure that they don’t accidentally open. I have loads of these in different sizes and they are all very useful and last ages. Easy to use and look good.

These are great, strong, robust and very easy to use. I bought it to fasten my sons water bottle on to his school bag when he started reception and its great. Holds well, copes with rough treatment without a problem but still easy for him to open.

Great size for keeping keys and key rings together , locking latches means no more lost items through unintentional opening in pocket or bag :)

Good sized carabiner and seems secure and well-made. Very useful for attaching a hat or an umbrella to a sling bag or rucksack. As someone else commented, it is possible to lose the little locking bands if you're not careful but the carabiner would still work without them.

Fantastic product. I use it to ‘lock’ the two zips on my backpack - it stops the bag opening and a small deterrent to pickpockets.

Very good, the little safety lock feature gives you confidence it will not loose your keys etc. Will likely buy another soon

This has quickly become a small piece of gear that I use every single day, makes clipping and unclipping items incredibly quick and convenient with the comfort of knowing it's more secure than a standard carabiner.

Vienen con un click de seguro soporta mucho peso

Solid item, does at intended but, don't expect it to bare higher loads.

Great

Hab ihn einer Bekannten für ihren riesigen Schlüsselbund geschenkt. Sie ist voll zufrieden

Best carabiner I've ever had. Easy to exchange keys and also keep them secure with the clip.
