[0016] Further purposes, features, advantages and possible applications will become apparent from the following description of some embodiments and the associated Drawings. The Figures 1a, 1b and 1c show a front and rear view of the connecting device, The Figures 2a, 2b and 2c show an exploded view of the Figures 1a, 1b and 1c , Figure 3 shows an exploded side view of the connecting device with screws, Figure 4 shows a side view of the screw connection device, and Figure 5 shows a side view of the screw connection device that connects two components. A device according to the invention is shown in Figure 1b designated by the reference number 100. Figure 5shows a connecting device 100 according to the invention in the assembled state. The connecting system according to the invention is realized by attaching a first connecting element consisting of a first part 101 and a second part 102. The first part 101 has a series of screw seats / holes 104 and advantageously a first part of a link 105a. The second part 102 also has a series of screw seats 104 and advantageously a second part of a connection 105b. The first part of the first element 101 has an end 106 housed in the seat 117 of the first part of the second element 111. The second part of the first element 102 has a seat 107 that receives an end 116 of the second part 112 of the second element.

[0017] Between the first part of the first element 101 and the second part of the first element, only one contact surface can be provided, which forms a stop between the two parts 101 and 102.

[0018] Each part 101 and 102 of the first element has a series of slots / holes 104 for fastening elements, which are preferably inclined toward the first part of the first element 101. Screws 201 are inserted into these holes for fastening the first element to a structural member 200. To facilitate fastening, holes 103 for positioning the element using screws may be provided.

[0019] The number of screws 201 of the second part of element 102, and thus also the number of inclined holes 104, is greater than the number of inclined holes in the first part of element 101. Thus, the forces transmitted by the screws on the second part of element 102 to the element are greater than the forces transmitted by the screws 201 on the first part of element 101. This creates a force, and this force on the connection is increased by the inclination and the number of screws 201. The connection between the two elements is not under tension, so it can also be a simple head-to-head connection, meaning the connection can also be formed by just two touching surfaces.

[0020] Each part 101 and 102 of the first element has a series of slots / holes 104 for fastening elements, which are preferably inclined toward the first part of the first element 101. Screws 201 are inserted into these holes for fastening the first element to a structural member 200. To facilitate fastening, holes 103 for positioning the element using screws may be provided.

[0021] The number of screws 201 of the second part of element 102, and thus also the number of inclined holes 104, is greater than the number of inclined holes in the first part of element 101. Thus, the forces transmitted by the screws on the second part of element 102 to the element are greater than the forces transmitted by the screws 201 on the first part of element 101. This creates a force, and this force on the connection is increased by the inclination and the number of screws 201. The connection between the two elements is not under tension, so it can also be a simple head-to-head connection, meaning the connection can also be formed by just two touching surfaces.

[0022] Each of the parts 111 and 112 of the second element has a series of slots / holes 104 for fastening elements, which are preferably inclined toward the second part of the second element 112. Screws 201 are inserted into these holes for fastening the first element to a structural member 200. To facilitate fastening, holes 103 can be provided for positioning the element on the structural member using screws 202.

[0023] The number of screws 201 of the first part of the second element 111, and thus also the number of angled holes 104, is greater than the number of angled holes of the second part of the second element 112, which is smaller. Thus, the forces transmitted to the element by the screws 201 on the first part of the second element 111 are greater than the forces transmitted by the screws 201 on the second part of the second element 112. This creates a force on the connection, and this force is increased by the number and / or inclination of the screws 201.

[0024] To facilitate assembly of the device 100 according to the invention, the two elements can be pre-assembled, for example, by means of connections 105, 115 formed by a protruding element 105a, 115a and a comfortable seat 105b, 115b. To fix the parts in position, at least one pin 108 is inserted for each element, locking the connection and facilitating assembly. In a variant not shown, the number of parts of the first element and / or the second element can be more than two, for example three, with at least one part having a greater number of screws 201 and / or screw seats 104 than the other parts of the element.
