6. A fastening device according to claim 1 , wherein the sliding element by means of the sliding element bearing and the locking element by means of the locking element bearing are supported on the holding base of the holding device so that they can move relative to one another and/or independently of one another.
7. A fastening device according claim 1 , wherein the sliding element and the locking element have a coupled movement.
8. A fastening device according to claim 1 , wherein the sliding element is spring-loaded in the direction of an external engagement position remote from the release position or in the direction of an engagement position with the holding member by a spring arrangement.
9. A fastening device according to claim 1 , wherein the locking element is placed under load by a spring arrangement in the direction of the locking position.
10. A fastening device according to claim 1 , wherein the row of teeth comprises teeth with a sawtooth configuration, having actuation slants for actuating the sliding element and/or the locking element in the direction away from the row of teeth or in the direction of a disengaged position.
11. A fastening device according to claim 1 , wherein the locking element has an actuating contour for actuating the sliding element in a form-fitting engagement or clamping engagement with the holding member.
12. A fastening device according to claim 1 , wherein the locking element through the holding member is actuated in a position that maintains the sliding element in a form-fitting engagement or clamping engagement with the holding member.
13. A fastening device according to claim 1 , wherein the actuating device for force amplification of an actuating force of an operator has a power transmission gear, between an operating area of the actuating device and the drive section of the sliding element.
14. A fastening device according to claim 13 , wherein the power transmission gear comprises a lever assembly or a lever gear.
15. A fastening device according to claim 1 , wherein the holding member is releasably removable from the holding device in the release position of the locking element.
16. A fastening device according to claim 1 , further comprising at least one guidance device for the holding member upstream or downstream of the locking element with respect to the displacement axis with a guide contour, which guides the holding member, secured against rotation, with respect to the locking element with respect to the displacement axis.
17. A fastening device according to claim 16 , wherein the at least one guidance device guides the holding member transversally to the displacement axis (V) and/or has a guide channel, the internal cross section contour of which corresponds to an external cross section contour of the holding member.
18. A fastening device according to claim 16 , wherein the at least one guidance device has at least one guide slant running at an incline to the displacement axis, in particular for impinging on free end areas of the teeth of the row of teeth or guiding the free end areas.
19. A fastening device according to claim 16 , wherein between the guide contour and the holding base a space serving as a working area for the sliding element is arranged.
