Abstract

A connecting system (1) has at least one connector (2) for a filter cassette (4) that can be inserted into a filter holder and has filter layers (5) between two end plates (6), and seals (7) between the filter layers (5) and/or between the end plates (6) and an adjacent filter layer (5). The connector has tensioning parts that engage in one another in a longitudinally displaceable manner and that can be fixed to the end plates (6) via their ends facing away from one another. The connector exerts a pretensioning force onto the end plates (6) when it is deflected to its maximum extent. The pretensioning force pulls the end plates (6) towards the filter layers (5), and when a contact-pressure force superimposed on the pretensioning force is applied to the end plates (6), the tensioning parts can be pushed towards one another correspondingly with the end plates (6).
