A snap-hook comprising: a hook-shaped body having a throat opening and a shank end, wherein the hook-shaped body includes a primary aperture located at the shank end suitable for attaching a primary line and a secondary aperture located approximately opposite the throat opening suitable for attaching a secondary line; and a dual-direction latch pivotally attached to the hook-shaped body such that the dual-direction latch spans the throat opening when in a neutral position and is capable of pivoting into and out of the throat of the hook-shaped body, wherein the dual-direction latch comprises a bent wire having two free ends, each end inserted in a different hole of two holes in the hook-shaped body that are non-axially-aligned resulting in a spring force that biases the dual-direction latch toward the neutral position and resists pivotal movement of the dual-direction latch both into and out of the throat.
