Les deux éléments de verrouillage 10, 20 peuvent être emboîtés l'un dans l'autre et être encliquetés l'un avec l'autre. Au moins un élément de blocage 12 permet d'encliqueter le premier élément de verrouillage 10 avec le second élément de verrouillage 20. L'élément de blocage 12 se prête à assurer l'encliquetage mécanique et peut être actionné et libéré par un actionneur 13. De plus, un organe de commande 15 est monté dans le premier élément de verrouillage 10 ou dans le second élément de verrouillage 20 pour assurer la sécurité de fonctionnement du dispositif de verrouillage 1. L'organe de commande 1 permet de libérer l'encliquetage des deux éléments de verrouillage 10, 20, même en cas de panne de l'actionneur 15. Le premier élément de verrouillage 10 et le second élément de verrouillage 20 sont destinés à être utilisés dans une fiche ainsi que dans une fiche homologue correspondante.
