Abstract: A keeper-equipped snap hook includes a guard member which can be readily positioned by a user in either a closed position or an open position. In the closed position the keeper is secured in a U-shaped channel provided by the guard member to protect the keeper from unintended or inadvertent actuation. In the open position the keeper is exposed for ready activation to an open position by the user to either install the snap hook on or remove the snap hook from a D-ring or the like. A cam actuator in the hook body and a camming surface on the guard member interact to bias the guard member in the open and closed positions for ease of use during installation or removal of the snap hook.
