Abstract: A mounting bracket for connecting two objects to one another. The mounting bracket includes an elongate protruding tongue element configured to be inserted in a cylindrical recess in one of the objects. The tongue element has one recess contacting side. A cross section of the tongue element on the recess contacting side is a circle sector with a radius, the other side of the tongue element being adapted to engage with a locking device. The locking device includes a cylinder and a lever connected to the cylinder. The cylinder is configured to be arranged in the recess adjacent the tongue element. The cylinder is configured to act as a cam when the cylinder is turned about its axis in the recess using the lever such that the cylinder is turned from a mounting position to a locking position in which a part of the locking surface pushes the tongue element such that the recess contacting side of the tongue element is in a pressing fit against the side of the recess.
