A connecting device for mounting a wooden construction element, in particular in the form of a panel or beam, on a support, the connecting device comprising - a mounting node, which is designed for mounting the connecting device on the support and - a coupling arrangement, which is connected to the mounting node and which, in the installed state, while projecting from the mounting node on an upper side of the wooden construction element, can be connected to the latter using fastening members, which at least partially pass through the wooden construction element, wherein the mounting node and the coupling arrangement are each produced from a material which has a higher strength than that of the wooden construction element, and wherein - the coupling arrangement is designed in such a way that it can be connected to the wooden construction element in each case along a fastening member axis by means of screw-shaped, pin-shaped or nail-shaped fastening members, in particular a self-drilling wood screw, - the coupling arrangement has fastening member bores, which determine the position and direction of the fastening member axes, characterized in that these fastening member bores are designed in such a way that, in the installed state, - the fastening member axis encloses together with a normal vector n extending from the underside of the coupling arrangement one angle of inclination θ each, which is 30° to 60° or about 45°, and - a direction vector s' of the projection of the fastening member axis on a coupling plane defined by the underside of the coupling arrangement encloses together with a radial vector r lying in the coupling plane a horizontal angle φ, wherein the radial vector r runs from a center O of the mounting node that is disposed in the coupling plane to a point of intersection P, in which the fastening member axis intersects the coupling plane, and - wherein the horizontal angle φ is 0° to +180° or 45° to 135° or -45° to -135°. - a mounting node, which is designed for mounting the connecting device on the support and - a coupling arrangement, which is connected to the mounting node and which, in the installed state, while projecting from the mounting node on an upper side of the wooden construction element, can be connected to the latter using fastening members, which at least partially pass through the wooden construction element, wherein the mounting node and the coupling arrangement are each produced from a material which has a higher strength than that of the wooden construction element, and wherein - the coupling arrangement is designed in such a way that it can be connected to the wooden construction element in each case along a fastening member axis by means of screw-shaped, pin-shaped or nail-shaped fastening members, in particular a self-drilling wood screw, - the coupling arrangement has fastening member bores, which determine the position and direction of the fastening member axes, characterized in that these fastening member bores are designed in such a way that, in the installed state, - the fastening member axis encloses together with a normal vector n extending from the underside of the coupling arrangement one angle of inclination θ each, which is 30° to 60° or about 45°, and - a direction vector s' of the projection of the fastening member axis on a coupling plane defined by the underside of the coupling arrangement encloses together with a radial vector r lying in the coupling plane a horizontal angle φ, wherein the radial vector r runs from a center O of the mounting node that is disposed in the coupling plane to a point of intersection P, in which the fastening member axis intersects the coupling plane, and - wherein the horizontal angle φ is 0° to +180° or 45° to 135° or -45° to -135°.
