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