Abstract of the Disclosure, Telecommunications cable with a splice closure covering conductors which have been severed and each having one severed end electrically connected to another cable. The other severed ends of the conductors are placed in series with a coil formed of electrical windings to enable a current to be passed through the coil by passing it through the electrically "dead" parts of the conductors to create an electromagnetic field around the coil to indicate the splice position. Preferably the coil is formed by windings passing around the cable and these windings may be embedded in the closure. - i -
