Another cable/connector/socket trick:

Turn the device upside down (screen at keyboard position; keyboard at screen position), put connector and socket close to each other (by repositioning the whole LCD) then use both hands, two pairs of tweezers and pull both ends of the steel clip carefully into the socket until its in place; then use the tip of the spudger and push left/right/left/right/.. end of the connector until your done. Finally close/secure the clip.

No need for going mad, no need for 4 hands.
