Abstract: A locking and latching snap hook, including an open hook body portion which is opened and closed to receive and discharge a to-be-connected item by movement of a normally closed, resiliently biased, latch member pivotally connected to the body. The hook body and latch member each generally carry a portion of one or more locking mechanisms which allows them to be releasably locked together to provide, along with the resilient bias latching, a locking capability to avoid inadvertent disengagement of the latch member from the hook body. The resiliently biased latch member extends beyond the body of the hook on the side opposite to the open hook end, and is capable of being selectively moved in a direction away from the hook end portion about the pivot to open the hook end portion of the body, when the locking mechanism is unlocked, and while simultaneously exerting pivoting force on the resiliently biased normally closed latch member.
