Various improved snap hooks having generally S-shaped bodies are used to engage spaced objects. In one embodiment, the snap hook has three sections; an eyelet, hook and hinged gate. The hook has a shank leading to a curved section that terminates in a receiving end. The receiving end has a notch on the lip of an inside surface. A metal wire gate extends from a supporting portion located on the eyelet and is biased closed against the notch. The gate has a long arm and a short arm, each terminating in a stem element. The gate is bowed to conform with the shape of the snap hook. When opened, the gate straddles either side of the shank so as to maximize the size of the aperture created when the gate is opened. In a first embodiment, the supporting portion is two supporting holes. The stem of each the long and short arms are inwardly turned so as to fit into respective supporting holes. In a second embodiment, the supporting portion is a single supporting hole. The stem of each the short arm and the long arm are inwardly turned. The stem of the short arm rests on the front surface of the eyelet and the stem of the long arm fits into the supporting hole. In another embodiment, the supporting portion is a single supporting hole. The stem of the short arm is inwardly turned and fits into the supporting hole. The stem of the long arm wraps around the base of the eyelet. The wrapped arm provide support to prevent lateral displacement of the gate. In additional embodiments, the gate is constructed of plastic material and includes a mounting structure that can be easily assembled onto the S-shaped hook. In all embodiments, the gate can be replaced when necessary.
