The electrical connecting device 1 comprises a first connection element 14 and a second connection element 13. The electrical connecting device 1 comprises a body element between the first connection element 14 and the second connection element 13. The body element extends in a main extension plane. In FIG. 2, the second connection element 13 is shown from the body element to the top of the figure and the first connection element 14 is shown from the body element to the bottom of the figure. The main extension plane of the body element corresponds to the plane of the drawing in FIG. 1. The first and second connection elements are oriented substantially orthogonal to the main extension plane of the body element.
It can be seen from FIG. 1 that the first connection element comprises four electrical connecting wires. The second connection element likewise comprises four electrical connecting wires.

This is shown in FIGS. 3 and 4 which show, respectively, side and top views of an assembly of three electrical connecting devices in accordance with the present invention, the electrical connecting devices being designated by the reference signs 1, 2 and 3. It can be seen that the male element of the first electrical connecting device 1 is inserted into the female element of the second electrical connecting device 2 and that the male element of the second electrical connecting device 2 is inserted into the female element of the third electrical connecting device 3. FIG. 3 also shows contact elements 51 of the support element 5, the first connection element of each of the electrical connecting devices 1, 2, 3 being attached to the support element 5, in particular by soldering, using the contact elements.
The first and second mechanical fastening elements 11, 12 can each have, in particular, a substantially round shape, but alternatively another shape is also possible, in particular a substantially triangular shape or a substantially rectangular shape or a substantially square shape or a substantially hexagonal shape.
Provision is made in accordance with the present invention that the first and second mechanical fastening elements are provided to allow a succession of several electrical connecting devices 1, 2, 3 in a first direction of the main extension plane of the body element of the electrical connecting device 1.
FIGS. 5 and 6 show, respectively, top and side views of an assembly of six electrical connecting devices 1, 2, 3 in accordance with another embodiment of the present invention. In this embodiment, the body element comprises a third mechanical fastening element (another male element) and a fourth mechanical fastening element (another female element) that are provided such that

    
    
        the third mechanical fastening element can cooperate with another fourth mechanical fastening element of another electrical connecting device for mechanical fastening between the electrical connecting device 1 and another of the electrical connecting devices 2, 3, and/or
        the fourth mechanical fastening element can cooperate with another third mechanical fastening element of another electrical connecting device for mechanical fastening between the electrical connecting device 1 and another of the electrical connecting devices 2, 3.
