I got the entire end of the charger stuck in so What I did is I got a pin [the kind that goes on bulletin boards] and I picked at the inside until the metal inside till it came out then I squashed what was left if it up [the cover's quite easy to bend] and pulled it out when it was small enough. This took roughly 3 minutes. I should probably also mention I have small hands so if you can't get your fingers in there you should use a pair of pliers. [I recommend the kind you use for splinters ].
Hope this works for you, good luck!
