is a part of a skydiving
harness-container system; a handle attached to a steel cable ending in a closing pin. The pin keeps the container closed and keeps the spring loaded pilot chute
inside. When the ripcord is pulled, the container is opened and the pilot chute is released, opening the parachute. On tandem
systems the ripcord releases the 3-ring release system
anchoring the bridle to the harness-container, allowing the parachute to open.
