4. The system according to claim 2, characterised in that the plate (22) comprises a side (25) arranged at a 90 degree angle.

5. The system according to claim 2, characterised in that the plate (22) comprises a longitudinal positioning stop (26) which is longitudinal with respect to the bar (21).

6. The system according to claim 5, characterised in that the longitudinal positioning stop (26) consists of a section bent at a 90 degree angle produced by means of die cutting the plate (22).

7. The system according to claim 1, characterised in that the bar consists of a hollow profile and the flat surface consists of a section of the bar.

8. The system according to claim 7, characterised in that said section consists of one end of the profile pressed into a laminar shape.

9. The system according to claim 7, characterised in that said section consists of a flat face of the profile, whether it be the face of a rectangular profile or that of a circular profile which has been flattened.

10. The system according to claim 1, characterised in that the width of the slot (23) decreases moving away from the opening (24).

11. The system according to claim 1, characterised in that the female element (2, 2) comprises more than one slot (23, 23) distributed in the longitudinal direction thereof.

12. The system according to claim 1, characterised in that the slot (23, 23) is double and symmetrical, the opening (24, 24) being located in the middle.

13. The system according to claim 12, characterised in that the opening (24) consists of a centered hole in the slot (23), with a size larger than the protuberance (13), wherein the slot (23) and the opening (24) are overlapping and form a single closed cut-out.

14. The system according to claim 3, characterised in that the plate (22) comprises a side (25) arranged at a 90 degree angle.

15. The system according to claim 3, characterised in that the plate (22) comprises a longitudinal positioning stop (26) which is longitudinal with respect to the bar (21).

16. The system according to claim 4, characterised in that the plate (22) comprises a longitudinal positioning stop (26) which is longitudinal with respect to the bar (21).

DESCRIPTION OF SPECIFIC EMBODIMENTS OF THE INVENTION

[0022] As shown in FIG. 1, a first preferred embodiment of the present invention when in use corresponds to an assembly made up of: [0023] a male element (1) joined to the head of a strut (p) and [0024] a female element (2) comprising a bar (21) with the upper end fastened to the male element (1) by means of a plate (22), and the other end joined to the lower area of the neighbouring strut, in this example by means of a wedge clamp.

[0025] As seen in FIG. 2, the male element (1) comprises a seat (11) for being joined to the head of the strut (p) and four pins (12) distributed at right angles to each other and containing a protuberance (13) at the end. As for the female element (2), it comprises a bar (21), for example which is solid and has a rectangular cross section, with a plate (22) comprising a slot (23), in this case being double and symmetrical, the longitudinal dimension of which is perpendicular to the longitudinal dimension of the bar (21). The slot in turn has an opening (24), in this case in the shape of a central hole, the diameter of which is larger than that of the protuberance (13), and which is overlapping with the slot (12), forming a single closed cut-out. In turn, the width of the slot (23) decreases moving away from the opening (24), from a width larger than that of the pin (12) to a width smaller than that of the latter, such that the pin (12) is fastened in the slot (23) shortly before reaching the end thereof.

[0026] In this first preferred embodiment, as seen in FIG. 3, the plate (22) comprises a side (25) folded at a 90 degree angle, as well as a longitudinal positioning stop (26) which is longitudinal with respect to the bar (21) consisting in this case of a section die cut at a 90 degree angle. The joining means between the bar (21) and the plate (22) in this embodiment, wherein the bar (21) is made of wood, consist of 6 screws.

[0027] In a second preferred embodiment of the female element (2), shown in FIG. 4a and FIG. 4b, the bar has a circular profile (21) comprising a longitudinal cut-out at the end wherein the plate (22) is inserted and fastened.

[0028] The details, shapes, dimensions and other accessory elements of the present anchoring system may be conveniently replaced by others that are technically equivalent without departing from the scope defined by the claims included below.
