Abstract
An exemplary slot closure arrangement has a sliding block and a pressure piece. At least one spring element is arranged in between them and can be prestressed by at least one attachment, which interacts with the sliding block and the pressure piece, thus creating a prefabricated assembly. Once the slot closure arrangement has been positioned in a slot, the attachment can be mechanically moved from a first position to a second position, which can be monitored, after positioning of the slot closure arrangement, for activation of the spring forces of the at least one spring element.
