lanyard

Description

 Usually it is used where there is a risk of losing the object or to ensure that it is visible at all times. Alternatively it is a length of cord or wire with a hook at the end used to fire an artillery piece, or to arm the fuze mechanism on an air-dropped bomb by pulling out a cotter pin (thereby starting the arming delay) when it leaves the aircraft. Aboard a ship, it may refer to a piece of rigging used to secure or lower things (see also halyard, lines used for lifting).
