the TAB puts a colon in , as your code instructed it to do, 
which now is interpreted as  " /: " and seen as a sign to invoke tramp, but
there is no hostname, so it exits with that error.

auto-completion does have its drawbacks sometimes with unintended
consequences. 

/hostname:/ will open a ssh-link to HOSTNAME and prompt you for a
passwd.

put in ~/.emacs:
;;; (setq shell-prompt-pattern ":") 

Wich means the prompt-pattern of the shell of the machine you connect TO.

Put this line (for unix) or some other Windows smb equivalent prompt 
in your .emacs is important here, otherwise tramp will wait 
(and block emacs) for minutes. 

You can preset some hosts like:
;;;(add-to-list 'tramp-default-method-alist '("hostname-1" "user1" "smb"))
;;;(add-to-list 'tramp-default-method-alist '("hostname-2" "user2" "ssh")
 ...
