[blindza] Interlocking metal disentanglement puzzle

One of the things got this weekend from a buddy is what they call an 
interlocking metal disentanglement puzzle - two separate pieces of metal bar 
that are bent into sort of matching shapes, and linked together in such a way 
that you have to fiddle around to figure out how to sort of line up their sort 
of opposite gap parts so that you can then slide them apart, and then rejoin 
them by sliding them back together and then start over trying to get the sort 
of solution right again a bit more quickly thereafter - took me like 10 minutes 
first time, and now seems to be doable/solvable within like a minute or two 
each time now that have sort of built up a 3D visualisation of the target 
alignment/juxtaposition in my mind's eye - has anyone else tried out this type 
of thing..?

Lastly, here's the wikipedia page mentioning this type of puzzle thing:
