Splicing device for closing a looped material band and material band provided with such splicing device

A material band (1) whereby this material band is looped, the material band (1) comprising:

• at least one splicing device (10) for facilitating looping of the material band (1) via two splicing elements (20, 30),
• at a first end of each of the two splicing elements (20, 30) facilitates intimately assembly, via an assembly area (21, 31), with a respective end of two longitudinal ends (2, 3) of the material band (1) and while as second end of each of the two splicing elements (20, 30) facilitates assembly together by two toothings (22, 23),
• each of the two toothings (22, 23) having a complementary shape and being provided respectively in a plane of the splicing elements (20, 30),
• teeth (13) of each of the two toothings (22, 32) comprising at least one transverse opening (14) aligned with that of neighboring teeth (13), in order to define, when toothings (22, 32) are fitted into each other, at least one transverse passage arranged for receiving at least one locking rod (15, 15a, 15b),
• wherein
• the splicing elements (20, 30) are made out of a thermoplastic material compatible with a material of the material band (1) and comprise at least one traction core (17) embedded in the thermoplastic material,
• the traction core (17) extends longitudinally in the splicing elements (20, 30) up to the teeth (13) of each toothing (22, 32),
• the traction core (17) at least partially surrounds the transverse opening (14) of teeth (13) of each toothing (22, 32) so that, when the splicing device (10) is assembled by at least one locking rod (15, 15a, 15b), the traction cores (17) increase a tensile strength of the splicing device (10),
• each splicing element (20, 30) comprises at least one traction core (17) extending between the assembly area (21, 31) and the toothing (22, 23) and forming a longitudinal turn or loop (19) at the toothing (22, 32), and
• strands of each longitudinal turn or loop (19) are arranged side by side with one another, without the overlapping one another, and lying within the plane of the two splicing elements (20, 30).
