Abstract: A toothed washer, in particular for fixing a tube line introduced in a fluid connector in an insertion direction, including an annular base having a toothed washer central axis. At the inner circumference of the base, cutting teeth are respectively disposed as a single component on the base radially inward and obliquely to the toothed washer central axis and extending in the insertion direction over an overmolded resilient hinge section and an overmolded retaining section connected thereto. The cutting teeth are configured such that in the event of a fixing movement of the tube line, the cutting teeth cut-in against the insertion direction into an outer circumference of the tube line, wherein the cutting teeth include a cutting surface for cutting into the outer circumference of the tube line to be fixed.

Furthermore, the disclosure relates to a method for producing a container using the fiber material, and container comprising the fiber material.

Abstract: The disclosure relates to a container comprising fibers, wherein the container further comprises a coating that is biodegradable. The disclosure further relates to a method for coating a container comprising fibers for producing the container.

Abstract: A connecting device having a connecting body with a receiving opening for a pipeline and a retaining element for securing an inserted pipeline. Inside the connecting body is a release element disposed in an axially displaceable manner such that the pipeline can be released. The release element includes a ring part and snap-in arms separated from each other by longitudinal slots. The outer perimeter the ring part can be sealed by an outer perimeter gasket against an interior perimeter wall of the connecting body, and the interior perimeter of the ring part can be sealed by an interior perimeter gasket against the inserted pipeline. In an assembled state of the connecting device, the outer perimeter gasket can be deformed from its sealing position such that at least one leakage gap is formed in the interior of the connecting device by an interior pressure of a pressurized medium in the pipeline.

Abstract: A connecting device for media lines including a coupling element, an insert part and a fastening element. The coupling element has a connection opening and a fluid channel; the insert part can be inserted into the connection opening; and the insert part can be fastened to the coupling element by the fastening element. The fastening element also has at least one control surface. When the insert part is inserted into the connection opening under the action of an installation force, the insert part acts upon the control surface in such a way that the fastening element is moved against a restoring force. If the installation force is sufficient, the insert part slides past the control surface and the fastening element interlockingly locks the insertion part. If the installation force is not sufficient, the fastening element presses the insert part back out of the connection opening.

Abstract: A connecting device for pipelines having a connecting body with a receiving opening for a pipeline with a line end to be inserted in an insertion direction and a retaining element seated within the receiving opening for securing of the inserted line end from being pulled out. Inside of the connecting body there is a sleeve-shaped release element disposed in an axially displaceable manner such that due to an action on the retaining element, the securing of the inserted pipeline can be terminated. The release element includes a ring part enclosed on the perimeter, and snap-in arms separated from each other by longitudinal slots that are formed thereon. On its outer perimeter the ring part can be sealed by an outer perimeter gasket against an interior perimeter wall of the connecting body, and at its interior perimeter in the region of its ring opening, it can be sealed by an interior perimeter gasket against the inserted pipeline.
