An apparatus for detecting the occurrence of an event, e.g. the presence of a liquid leak. The apparatus includes an elongate flexible core consisting of elongate elements which are twisted together. The elongate elements comprise first and second sensing members, which each have an electrically conductive outer surface and are physically separated from one another, and at least two elongate insulating members. These elongate elements are covered by a flexible braid which exerts a compressive force on the core. In one aspect of the invention, the flexible braid undergoes a reversible change in appearance when exposed to electrolyte, indicating the location of a leak.
