A fitting for connecting two structural components. The fitting includes a locking device mounted on the first structural component and a support device mounted on the second structural component. A rotary member in the support device defines circumferentially extending conical surface against which the front end of the locking device is pressed when the two fitting devices are connected. The force exerted by the front end of the locking device causes the rotary member to be turned. The rotary member has a helical end face which is initially outside of the range of travel of the locking device. Upon turning of the rotary member, the helical end face comes into engagement with a countersurface of the locking device. The resulting connection can only be released by means of a tool. The structural components are pressed tightly together by a further turning of the rotary member. A piece of furniture composed of several structural components can be initially connected without the aid of a tool and can subsequently be tightened after the piece of furniture has been assembled. The fitting makes possible the connection of structural components where the tolerances in assembling the fitting devices are inaccurate or have been exceeded. |
