fphttpclient already does that before calling connect and it doesn't work.

As Michael said, the socket must be put in non-blocking mode during the 
connection. This is how synapse does it (but I see that ssockets has no 
provision for toggling between blocking/non-blocking mode):

     if FConnectionTimeout > 0 then
       // connect in non-blocking mode
       b := NonBlockMode;
       NonBlockMode := true;
       SockCheck(synsock.Connect(FSocket, Sin));
       if (FLastError = WSAEINPROGRESS) OR (FLastError = WSAEWOULDBLOCK) 
         if not CanWrite(FConnectionTimeout) then
           FLastError := WSAETIMEDOUT;
       NonBlockMode := b;
       SockCheck(synsock.Connect(FSocket, Sin));
