The joint has a sliding cylinder (7) having a revolutional axis coaxial with a hinge`s rotational axis and extends on the length of the hinge, where the hinge and the cylinder are situated at an outside of an inner compartment e.g. fixed concrete mixer drum. A flexible longitudinal joint (8) has an axis parallel to the rotational axis and is situated at a constant radius (R) with respect to the hinge.
