Double locking snap hook device

A snap hook device comprising:

• a hook member including a hook throat opening formed therein and defined by a hook portion and a shank, and including a compartment formed therein and located opposite to said hook throat opening of said hook member,
• a hinged gate pivotally coupled to said shank of said hook member with a pivot pin for openably closing said hook throat opening of said hook member,
• a first spring biasing member disposed between said hinged gate and said shank of said hook member for biasing and forcing said hinged gate to close said hook throat opening of said hook member, and arranged to allow said hook throat opening of said hook member to be selectively opened when said hinged gate is depressed onto said spring biasing member and forced toward said shank of said hook member,
• a latch member pivotally coupled to said shank of said hook member with a pivot axle for openably closing said compartment of said hook member, said latch member including an anchor member extended therefrom, and
• a second spring biasing member disposed between said latch member and said shank of said hook member for biasing and forcing said latch member to close said compartment of said hook member, and arranged for allowing said compartment of said hook member to be selectively opened when said latch member is depressed onto said spring biasing member and forced toward said shank of said hook member, said second spring biasing member being provided for biasing and forcing said anchor member of said latch member to engage with said hinged gate and to lock said hinged gate to said hook member, and to prevent said hinged gate from being depressed and actuated and forced toward said shank of said hook member and to prevent said hook throat opening of said hook member from being opened inadvertently before said anchor member of said latch member is disengaged from said hinged gate.
