Hollow-cylindrical base element of a connecting unit

A hollow-cylindrical base element of a connecting unit for connecting a first component to a second component with a distance therebetween, comprising:

• a. an outer side and a threadless inner side,
• b. adjacent to a first axial end, a first drive feature and a first inner diameter,
• c. between the first axial end and a second axial end arranged opposite to the first axial end and following a flange at the first axial end, a first outer thread which, when used in the first component, is in engagement therewith, wherein
• d. a section with the first inner diameter transitions with a step into a connecting section terminating with the second axial end so that the connecting section is present between the step and the second axial end, and the hollow-cylindrical base element further comprises:
• e. a pivoting element comprising a ball segment section as well as a cylindrical section and having a threadless passage opening which has a second inner diameter which is smaller than the first inner diameter, wherein the cylindrical section is arranged at the ball segment section facing away from the first axial end such that, when in use, the cylindrical section provides an abutment face for the second component, wherein,
• f. the pivoting element is provided adjacent to the second axial and the connecting section is adapted to the ball segment section so that the pivoting element is in engagement at least partially with the threadless inner side of the hollow-cylindrical base element in the area of the connecting section and in such a form-fitting manner that it
• f1. is immovable in either axial direction along a longitudinal axis of the base element so that the pivoting element cannot be released from the base element without destroying the base element,
• f2. is non-detachably connected to the base element along the longitudinal axis, and
• f3. is pivotable relative to the longitudinal axis of the base element, and
• g1. the pivoting element is circumferentially completely surrounded by the base element or
• g2. the base element comprises a radial cutout or clearance adjacent to the second axial end which is dimensioned such that the pivoting element can be clipped in laterally relative to the longitudinal axis of the base element.
