A carabiner includes a body having a first arm extending from the body and a second arm extending from the body, a first gate pivotally coupled to the body adjacent the first arm for movement relative to the first arm, and a second gate pivotally coupled to the body adjacent the second arm for movement relative to the second arm. The carabiner also includes a blocking member supported by the body. The blocking member is movable between a first position, in which the first and the second gates are movable relative to the first and second arms, a second position, in which the first gate is inhibited from moving relative to the first arm and the second gate is movable relative to the second arm, and a third position, in which the first and the second gates are inhibited from moving relative to the first and second arms.
