Abstract
A connecting device for detachable connection of two perpendicularly positioned panels, such as furniture panels, by means of a grooved fastener bolt fastened in the first panel and a tightening bolt rotatably mounted in a blind bore of the second panel. The tightening bolt is mounted in a first blind bore in the second panel and the fastener bolt is adapted to be inserted into a second blind bore in the second panel perpendicular to the first bore. The tightening bolt is in operative engagement with the head of the fastener bolt in such a manner that as the tightening bolt is rotated the fastener bolt is pulled into the second blind bore firmly joining the two panels.
