Window Part, spring inside

Hello, I am a contractor in Northern Virginia. I have heard good things about your company. The part I have attached is a spring loaded part that pulls to release the window. There is one on each side of window that must be pulled in together before window can come up. The part in pic is broken, the hook thing actually comes all the way around to make a full loop. and the piece on the other side that hooks into the dide of window is broken off too. I need 4 or 5 of these. Thanks again.
