Hi guys, can anyone tell me which connection I can use for off camera flash with my canon eos 620?

This a link to flash accessories on 7dayshop.com. I think it might be the last product on the bottom of the page (Nissisn Universal Flash Shoe Cord) but I'm not sure. And I don't want to spend £35 if it's the wrong one.

Thankyou.
