La bande de clôture électrique (100) inclut au moins deux conducteurs électriques essentiellement dénudés situés à une première l'un par rapport à l'autre ; ces conducteurs électriques forment deux groupes de conducteurs (110a, 110b). Le système comprend également un dispositif de clôture électrique (105), qui est disposé pour générer une haute tension pulsée entre les deux groupes de conducteurs (110a, 110b) de la bande de clôture électrique (100), et au moins deux câbles de contournement (301a, 301b) pour contourner un obstacle (300) dans le bâtiment. Les câbles de contournement sont prévus pour être fixés par l'une et l'autre de leurs extrémités aux groupes de conducteurs (110a, 110b) de la bande de clôture électrique (100) au moyen de connecteurs (303) de sorte que le câble de contournement (301a ; 301b) et le groupe de conducteurs correspondant (110a ; 110b) de la bande de clôture électrique forment un circuit électrique homogène, et le câble de contournement (301a, 301b) comprend un conducteur de courant entouré d'un matériau isolant. Le nuisible contre lequel il faut lutter reçoit une décharge électrique de la bande de clôture électrique lorsque le nuisible touche simultanément l'un et l'autre des groupes de conducteurs.
