regex - Extract stuff between the first pipes in bash? -

i want extract stuff in between first 2 pipes:

| a650f360-a29d-4562-b46f-024fe15aa7dc | emi-ubuntu-12.04.2-server-amd64-08152013           | active |

the output should be:

 a650f360-a29d-4562-b46f-024fe15aa7dc

i have regex going use sed with: ^\|\s*(.*?)\s*\|

but according regex calculator gets me pipes well. how rid of it?

sed 's/^[^|]*|\([^|]*\)|.*/\1/'

that matches non-pipes @ beginning (nothing in example data), pipe, captures stuff isn't pipe, matches pipe , @ end, , replaces captured stuff.
