Abstract
A self locking snap hook that includes a central shank having an arch shaped hook member that defines a gateway opening at one end, a gate keeper enclosing the gateway opening, a locking lever to prevent the opening of the gate keeper, and a second locking mechanism having an engaged and a disengaged position such that when it is engaged it prevents the locking lever from being disengaged. Movement of the second locking mechanism between its engaged and disengaged positions requires the application of force and resulting movement in a direction other than that required to move the locking lever from its engaged to its disengaged position.
