The connecting member according to  claim 4 , further comprising a connecting portion at at least one end of said body portion, said connecting portion providing a further component, at least one connecting portion at least partially being made of a second material, said first material having a higher density than said second material. 
     
     
         6 . The connecting member according to  claim 5 , wherein said second material is plastics material and said first material is metal material or plastics material. 
     
     
         7 . The connecting member according to  claim 4 , wherein at each end of said body portion a connecting portion is provided. 
     
     
         8 . The connecting member according to  claim 4 , wherein at least one connecting portion is provided as a component made of one material and/or wherein said body portion is provided as a component made of one material, and/or wherein a second component is embedded into the material of the body portion providing a first component and is made of a material having a higher density than the material of the body portion. 
     
     
         9 . The connecting member according to  claim 4 , wherein said body portion is provided in a component made of at least two pieces, at least one of said pieces being made of metal material and/or at least one of said pieces being made of plastics material. 
     
     
         10 . 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. 
     
     
         11 . The connecting member according to  claim 9 , wherein said component comprises said plate-shaped body portion and at least one plate-shaped additional mass member made of metal material. 
     
     
         12 . The connecting member according to  claim 4 , wherein at least one connecting portion is integrally cast to said body portion, and/or wherein at least one connecting portion is fixed to said body portion by positive locking, and/or wherein at least one connecting portion is fixed to said body portion by gluing, and/or wherein said connecting portions are provided as integral portions of said body portion. 
     
     
         13 . The connecting member according to  claim 1 , wherein at least one of said components is arranged for connecting to a pulley of a tackle member of a shed forming mechanism for a weaving machine, and/or wherein one of said components 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 a pulley of a tackle member of a shed forming mechanism for a weaving machine is rotatably carried. 
     
     
         15 . The connecting member according to  claim 1 , 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/cm 3  to 1.5 g/cm 3 . 
     
     
         16 . (canceled) 
     
     
         17 . Tackle member for a shed forming mechanism for a weaving machine, comprising at least one connecting member and at least one pulley rotatably connected to said at least one connecting member, wherein the connecting member comprising at least two components made of materials having different densities. 
     
     
         18 . The tackle member according to  claim 17 , wherein at least one axle member providing a component of at least one connecting member and rotatably supporting a pulley is carried by another component of at least one of said connecting members. 
     
     
         19 . A shed forming mechanism for a weaving machine, comprising at least one connecting member wherein the connecting member comprising at least two components made of materials having different densities. 
     
     
         20 . The shed forming mechanism according to  claim 19 , wherein one of said components of at least one connecting member is connected to a tackle cord and another one of said components of the same connecting member is connected to at least one harness cord or heddle.
