Abstract: A spreader structure for a ring seal for sealing an annular gap, includes a radially inner first component with an inner contact surface, a radially outer second component with an outer contact surface, and a first spreading mechanism formed between these two components that includes a first spreading bevel formed on one of the two components, and a first spreading element formed on the other component, that can be moved along the first spreading bevel. The two components can be displaced in relation to one another, from an assembly state to a spreading state, by means of which the first spreading element is moved from a first section of the first spreading bevel to a second section of the spreading bevel, enlarging a radial spacing between the inner contact surface and the outer contact surface. The spreader structure has a second spreading mechanism.

Abstract: A device for connecting two pipes with different external diameters using a sleeve arrangement which bridges the butt joint between the ends of the pipe facing each other. The device contains at least a fixing sleeve which can take up the clips for the two pipes, and, if necessary, a sealing sleeve which is surrounded by the fixing sleeve.

Abstract: A clamping device (1) for bridging two elements (2a, 2b, 200a), which can be brought closer to each other, with at least one tensioning belt (6, 60) connected with an element (2a, 200a). The tensioning belt engages into an allocated turnbuckle (4) connected with the other element (2b) and is movable with it. The tensioning belt (6, 60) and the turnbuckle (4) are each mountable on the allocated element (2a, 2b, 200a) by a positive plug-in connection. The elements, which can be brought closer to each other (2a, 2b, 200a), are provided with formed retaining structure (10, 100) defined as projections emerging from their plane. The end portion of the tensioning belt (6, 60) facing away from the turnbuckle (4) and a turnbuckle belt (5) defined as a belt lug being applied on the turnbuckle (4) and in opposite direction to the tensioning belt (6, 60) are provided with counter-retaining structure (13, 130) which can be attached on the retaining means (10, 100) of the elements.
