Hi Frenchyfri212, and welcome to Chordie!
I think the proper answer is YES.... like most electric guitars, acoustic/electrics usually have a 1/4" TS female plug in the body and it is retained by a threaded collar or nut of the proper size. Not knowing your home "planet", if it is here in the US, your local Radio Shack store should be able to sell you a replacement nut fairly cheaply. Most stores that sell or repair guitars will have a couple laying around I'm sure if Radio Shack is not an option. Use caution installing it however as the threads are fine and the nut thin and prone to stripping, so go easy, and you might apply a dab of clear nail polish to it to prevent it loosening again.
Take Care and have fun visiting Chordie... there are lots of good folks here.
