The connecting member according to one of claims 1 to 3, wherein one of said components (14; 54a; 14b) comprises a preferably elongated body portion (20; 52a; 20b) at least partially made of a first material.

The connecting member according to claim 4, further comprising a connecting portion (26, 28) at at least one end of said body portion (20), said connecting portion (26, 28) providing a further component (16, 18), at least one connecting portion (26, 28) at least partially being made of a second material, said first material having a higher density than said second material.

The connecting member according to claim 5, wherein said second material is plastics material and said first material is metal material or plastics material.

The connecting member according to one of claims 4 to 6, wherein at each end (22, 24; 22b, 24b) of said body portion (20; 20b) a connecting portion (26, 28; 26b, 28b) is provided.

The connecting member according to one of claims 4 to 7, wherein at least one connecting portion (26, 28) is provided as a component (16, 18) made of one material, preferably is provided as a component (16, 18) made of one piece, and/or wherein said body portion (20) is provided as a component (14) made of one material, preferably is provided as a component (14) made of one piece, and/or wherein a second component (70b) is embedded into the material of the body portion (20b) providing a first component and is made of a material having a higher density than the material of the body portion (20b).

The connecting member according to one of claims 4 to 8, wherein said body portion (52a) is provided in a component (54a) made of at least two pieces (52a, 70a), at least one of said pieces (70a) being made of metal material and/or at least one of said pieces (52a) being made of plastics material.

The connecting member according to claim 9, wherein said body portion comprises a core member made of plastics material and a sleeve member made of metal material and surrounding said core member.

The connecting member according to claim 9, wherein said component comprises said preferably plate-shaped body portion (52a) and at least one preferably plate-shaped additional mass member made of metal material.

The connecting member according to one of claims 4 to 1 1 , wherein at least one connecting portion (26) is integrally cast to said body portion (20), and/or wherein at least one connecting portion (28) is fixed to said body portion (20) by positive locking, and/or wherein at least one connecting portion (28) is fixed to said body portion (20) by gluing, and/or wherein said connecting portions (26b, 28b) are provided as integral portions of said body portion (20b).

13. The connecting member according to one of claims 1 to 12, wherein at least one of said components (62a, 64a, 66a), preferably made of metal material, is arranged for connecting to a pulley (42a, 44a, 46a) of a tackle member (40a) of a shed forming mechanism for a weaving machine, and/or wherein one of said components (16, 18), preferably made of plastics material, is arranged for connecting to a tackle cord or at least one harness cord or heddle of a shed forming mechanism for a weaving machine.

14. The connecting member according to claim 13, wherein on at least one of said components (62a, 64a, 66a), preferably made of metal material, a pulley (42a,

44a, 46a) of a tackle member (40a) of a shed forming mechanism for a weaving machine is rotatably carried.

15. The connecting member according to one of claims 1 to 14, wherein the density of a material having a higher density is at least 120% of the density of a material having a lower density, and/or wherein the density of a material having a lower density is in the range of 0,9 g/cm3 to 1 ,5 g/cm3.

16. Cord connector for connecting a tackle cord to at least one harness cord or heddle of a shed forming mechanism for a weaving machine, comprising a connecting member (10) according to one of claims 1 to 15.

17. Tackle member for a shed forming mechanism for a weaving machine, comprising at least one connecting member (48a, 50a) according to one of claims 1 to 15 and at least one pulley (42a, 44a, 46a) rotatably connected to said at least one connecting member (48a, 50a).

18.
