Replacing oven broil element. Will this replacement work?
I would be looking for high temperature female spade fittings similar the one below that fits onto your heating element and crimp them on to your wires. My advice would be to take your element into an appliance repair store and get the fittings there so you get the right type and size. You will probably have to buy a crimping tool unless you can talk the guy into letting you borrow his.
You could also remove the wires from the back and have the appliance guy crimp the fitting on the wires and them reinstall them in your oven... just remember how to hook them back up.
