A device for detachable joining of two essentially square-shaped structural components (13), of which the one has a regrippable edge and the other has a cavity using a connector piece at the other end for joining the pieces together. This is comprised of a casing with a first hole for reception of a tension body. The tension body has a hook (6) at its one end for interference with the said edge as well as a slanted surface (8) on the part of it which is inserted into the casing for co-operation with a movable cross-body tension screw (9), which is received in a second, directed across the first hole and threaded hole (4) in the casing. The casing (1) is cylindrical with the cylinder axel parallel with the first hole's longitudinal axis and has an outer thread for threading action with at lease two part areas of the cavity's two mentioned walls.<IMAGE> |
