Description:
BACKGROUND OF THE INVENTION  
         [0001]    1. Field of the Invention  
           [0002]    The invention relates to a transfer connection device for wirelessly connecting mobile phone and hand-free handset that has a first connector and a second connector to couple respectively with a hand-free handset and a mobile phone to communicate control signals therebetween without physical lines.  
           [0003]    2. Description of the Prior Art  
           [0004]    Deregulation of telecommunication industry has made mobile phones very popular nowadays. The peripheral communication devices to couple with mobile phones also are flourishing.
