Not the standard Red Blue Yellow crimps you get from electrical supply shops. As the novocaine said these are the higher quality types used in automotive manufacturing. Much more complicated, more spring, more reliable contact. If you only want a couple, you might try and make friends with a local (main dealer) car service department who should have spares of stuff fitted in the factory. Otherwise Rapid Electronics or search RS Components and Farnell.
These fall in the broad category of uninsulated crimp connectors - you do insulate them but the plastic shell or cover is a separate part holding one or several of these connectors. Note that you won't be able to crimp them to the wire properly using a standard tool made for the Red/Blue/Yellow type.
They are sometimes used on factory original car radio connectors. That's one place where I've seen them used before.
And this kind of thing does come in different sizes for different current ratings. It would be sensible to measure the width and try to check.
