You can see the type of shackle quite clearly. In the UK you can get these shackles from Sailspar, but I don't know who would supply them wherever you are. A good starting point would be your local chandler who might be able to order one in for you.

BTW. VERY important that knot is on the back of the shackle (away from the hook)
