Can anyone tell me where the horn is located on a saxo. Some say drivers wing others bumper. I cant find it?

my car horn has a intermittent fault with the horn.Im sure its just a loose wire. I cant find the horn under the bonnet. I have a saxo Forte 02 plate. I've tried the suggested behind the bumper and inside the engine compartment on the drivers wing. maybe I just dont recognise it. Can anyone help. maybe with a photo!
