The disclosed swivel adaptor (20) is assembled into two sections: tool member (40), and adaptor member (60). These two sections are pivotally attached, and can pivot with respect to each other around pivot axis (54). Pivot axis (54) is angled off-axis with respect to the longitudinal axises of the adaptor sections to allow various angled positions for adaptor (20). The angle between the tool port end (42) and adaptor port end (64) being adjustable between an in-line position where members (40) and (60) form a relatively straight adaptor, and a plurality of angled positions where the longitudinal axises of ports (42) and (64) are not parallel. Adaptor (20) has an pivotal air passageway connecting end (45) to end (65). In the straight position, tabs (72) snap into place to provide a holding force to keep the two sections from pivoting during use. By applying a sufficient twisting force on the two sections, tab (72) slips loose and the two sections can rotate about axis (54). Tool member (40) is designed to fit into standard vacuum cleaner nozzles. Adaptor member (60) is designed to fit onto both vacuum wand hoses and vacuum wand ports.

A device as set forth in claim 15, wherein the small lamella biasing means comprises one of upper and lower legs of respective small lamellas which limit indentations provided on inner sides of central openings of the small lamellas, compression beams supported in the projection of the first clamping plate in a region of the indentations, and compression springs for biasing the compression beams, and wherein an upper compression beam lies on each second of the upper legs of the small lamellas and is spaced from the upper legs of respective intermediate small lamellas by respective indentations of the respective upper legs, and a lower compression beam lies on each second of the lower legs of the intermediate small lamellas and is spaced from the lower legs of the small lamellas which it does not engage by indentations of the non-engagable lower legs. 17. A device as set forth in claim 16, wherein the guide member pivots relatively the bracket about a horizontal axis extending transverse to the steering shaft for effecting the height adjustment of the steering column. 18. A device as set forth in claim 1, wherein the large lamellas each have sidewise projecting spring arms located outside of a circumferential profile of respective small lamellas and supported against a side wall of respective adjacent large lamellas. 19. A device as set forth in claim 1, wherein in order to prevent an excessive tilting of the lamella stack in the open position of the locking device, the large lamellas are provided with side elevations extending above one of their respective side surfaces, each side elevation extending above a respective side surface of a respective large lamella by a distance corresponding to a thickness of a small lamella. 20. A device as set forth in claim 1, further comprising means for biasing the large lamellas in a direction of the height adjustment of the steering column and which permits to reduce backlash when a large adjustment force is applied to the steering column in the direction of the height adjustment in the closed condition of the first adjusting device, where
