Tilt latches

A piece broke off of the side of the latch and the latch will no longer stay on the window. As a result, the window is coming out of the window. I have attached pictures of the front and back of the latch and a picture of one of the latches that is still in the window. Hope that is helpful. The main body of the latch (the part without the pointed end) is 2 5/16 inches long and 3/4 inches wide. I would appreciate any assistance you could provide in identifying what part I need.
