A fastening unit comprising two holding parts (5, 6), each insertable in a respective seating (2, 2') being provided with a slit (3), said holding parts being interconnected by articulated links. At least one holding part (6) comprises two spaced-apart blocks (7, 8) that, one after the other, can be inserted in one and the same seating (2') and that are interconnected by a bolt element that can be accommodated in the same seating as the blocks, by the means of which the blocks can be approached to respectively distanced from each other in order to on one hand in a releasing position, keep the two holding parts (5, 5') at a comparatively large distance from each other and, on the other hand, in a fastening position, force the holding parts closer to each other whilst clamping two associated seatings (2, 2') against each other. |
