           The security cable  300 includes a cable  310 of the type   which corresponds to a number of oscillations which is the
         illustrated in figure 7 and described above, and a coupling
         320 connecting the two cable ends 312 to one another. The
         coupling  320  includes  two  coupling  portions  322,  each  of
         which is attached to one of the cable ends 312. When the cou-
         pling portions 322 are attached to one another, the coupling
         320 selectively prevents separation of the two portions 322,
         thereby maintaining the cable ends 312 in close proximity to
         one another. It should be appreciated that the coupling 320
         is illustrated in schematic form since many configurations of
         couplings are contemplated for use with the security cable
         300. Illustrative forms of the coupling 320 are described be-
         low with reference to figures 9-11.
