Your code snippet doesn't tangle at all here.  Perhaps you have a  
setting somewhere that has an effect on tangling?

This one does tangle:

* Nicolas Girard
#+srcname: a
#+begin_src emacs-lisp
(a)
#+end_src

#+srcname: b
#+begin_src emacs-lisp :tangle test.el
<<a>>
(b)
#+end_src

It yields:

;; generated by org-babel-tangle
;; [[file:~/Public/projects/worg/Worg/babel-doc/test.org::*Nicolas 
%20Girard][b]]
(a)
(b)
;; b ends here

Is this what you're after?

HTH,
Tom
