A shoulder is arranged on one of the label and the label holder. A locking arm (70) locks the label in the inserted position by cooperation with the shoulder. The locking arm moves between a locked position and an unlocked position by a displacement parallel to the front face and without any displacement in a direction perpendicular to the front face. An independent claim is also included for a method for replacement of a label of an entrance intercom.</p> |
