Abstract: A transmission device comprises an output element and a drive element comprising a drive body made from a first material, from a plastic. The drive body comprises a drive region and a connecting region. The output element engages into the connecting region that comprises positively locking structures which transmit a torque to the output element, the connecting region is configured such that the positively locking structures are radially movable, resulting that the output element is rotatable relative to the drive body with widening of the connecting region. The drive element comprises a compression element which preloads the drive body inwards in the radial direction in the connecting region, wherein the compression element is formed from a second material different from the first material and is elastic in the region of the widening portion and has a higher spring stiffness than the connecting region of the drive body.

Abstract: A connecting element for mechanically connecting at least two components has a closure head for abutment against a first component and having a closure foot for abutment against a second component and for bracing the latter against the first component in a rotated final-mounting position. A stem portion extends between the closure head and the closure foot, which is spaced apart axially from the closure head in the longitudinal direction of the stem. The closure head has a sealing surface that extends in the longitudinal direction of the stem portion and sealingly abuts against a corresponding sealing surface of a recess in the first component. There is also described a connecting arrangement with a first component and at least one second component and a corresponding connecting element. The latter may be made from a single material component.
