A filling tube assembly for being mounted to a clipping machine for producing sausage-shaped products, like sausages, the filling tube assembly comprising: - a mounting unit for mounting the filling tube assembly to the clipping machine; - a filling tube for feeding flowable filling material in a feeding direction into a tubular or bag-shaped packaging casing being consumably arranged on the filling tube, wherein the filling tube has a filling inlet for receiving the filling material, a filling outlet for discharging the filling material into the packaging casing and a filling tube axis extending between the filling inlet and the filling outlet, and wherein the filling tube is pivotable relative to the mounting unit around a pivot axis at least between a production position and an interchanging position; and - a casing brake unit with a brake axis, a casing brake holder and a casing brake for being reversibly coupled to the casing brake holder, wherein the casing brake holder is configured for reversibly holding the casing brake on the filling tube in a braking position, in which the brake axis is at least basically coaxial with the filling tube axis, wherein the casing brake holder together with the casing brake is moveable between the braking position and a releasing position by a pivoting and translational action, and wherein, in the releasing position, the casing brake holder together with the casing brake is pivoted away from the filling tube in a way that packaging casing to be filled can be loaded onto the filling tube; characterized in that the casing brake unit further comprises: - a first holding device with a first holding axis, the first holding device is coupled to the filling tube in a way that a pivoting action of the filling tube around the pivot axis causes the same pivoting action of the first holding device around the pivot axis, wherein the casing brake holder is pivotably arrangeable at the first holding device for pivoting relatively to the first holding device at least in a section between the braking position and the releasing position, and wherein the casing brake holder is movable along the first holding axis; - a second holding device for guiding the casing brake holder with the casing brake along at least two guiding means, wherein the casing brake holder and/or the casing brake comprise at least one corresponding engaging means for each guiding means for engaging with a respective guiding means, wherein the guiding means are configured for causing a translational movement of the casing brake relative to the filling tube when moved between the braking position and a turning position and for causing a pivoting action of the casing brake relative to the filling tube when moved between the turning position and the release position, when the filling tube is pivoted between the production position and the interchanging position. - a mounting unit for mounting the filling tube assembly to the clipping machine;
