ABSTRACT This invention provides a connecting member which comprises a cylindrical box formed from two identical cup-shaped connecting pieces having a centering cams uniformly distributed around the periphery thereof, and a wedge-shaped hook in each case located in the central area thereof. There is also provided a method of producing a detachable connection between two surfaces which is invisible from the outside. At least one surface belongs to a movable component, and at least one circular, box-shaped connecting member is used. The connecting member comprises two circular, cup-shaped connecting pieces each having a wedge-shaped hook projecting from the cup shape. The facing connecting pieces are so fixed to the two surfaces to be connected that the hooks, which are displaced from one another by 180°, on laterally sliding together the connecting pieces hook into one another to form the box-shaped connecting member thereby interconnecting the two surfaces. At least one of the two connecting pieces being located in a previously drilled, circular bore from which only the hook projects. At least one circular bore is drilled at a predetermined point on the surface of the first component, and in a marking gauge having a projecting centering tip which is adjustable in height is placed in the bore. The first component is pressed in a predetermined position against the surface of the second component so that the centering tip leaves behind a visible impression to aid location of a respective connecting piece on the second component.
