Abstract: An ergonomic snap hook that employs a recessed release to prevent undesirable unfastening. The snap hook uses a redundant locking gate that must be operated in a predetermined sequence to permit latch opening. Once the latch is opened, a rope or the like may be inserted into the hook to secure the user thereto. The snap hook is fastened to a supporting belt or strap which, in turn, is connectable, by the hook, to a body belt worn by the linemen. A spring biased, recessed gate prevents latch movement until the gate is released. Preferably, the gate mounts opposite of the latch. To unfasten the latch, the user first depresses the gate to align a follower on the latch with a slot opening on the gate. Subsequent follower movement along the slot coincides with latch release. The followers on the latch clean the slots on the gate as they move along them. The latch may then be opened by applying an appropriate pressure or force against the latch biasing spring. The gate may be easily manipulated with one hand.
