A separation element including a panel and a connecting device for use with an adhesive. The connecting device includes at least one profile strip and a separation profile. The profile strip includes a back element, a first side element and a second side element that together define a mounting channel, and an anchor channel defined by the profile strip. The anchor channel is connected to the mounting channel by a through slot. The mounting channel is configured such that the edge of the panel is held within the mounting channel by means of the adhesive. The separation profile separates the profile strip from the panel, and it includes a middle part, a first side part, and a second side part and defines at least one window opening that functions to allow the adhesive to penetrate into the anchor channel.
