         24 . A tie rod for joining together opposite side sections of a formwork, said tie rod comprising:
 a mid portion;   two rod end portions having a rest for a wedge device for securing the side sections of the casting formwork; and   at least one abutment surface located between said mid portion and either rod end portion, said abutment arranged to rest supportingly on an internal side surface of the side sections,   wherein said tie rod includes a stem of great tensile strength with a surrounding mantle, said mid portion and said mantle of said stem being a continuous structure of a non-corrosive material.   
     
     
         25 . The tie rod in accordance with  claim 24 , further comprising said tie rod formed of a composite material. 
     
     
         26 . The tie rod in accordance with  claims 24 , said stem comprising fibre-reinforcement in an axial direction of said tie rod. 
     
     
         27 . The tie rod in accordance with  claims 24 , further comprising said mantle and said mid portion formed of the same type of material. 
     
     
         28 . The tie rod in accordance with  claims 24 , further comprising said mantle and said mid portion are joined by fusion of a material forming said mantle and a material forming said mid portion. 
     
     
         29 . The tie rod in accordance with  claim 24 , further comprising said mantle and said mid portion joined by glue. 
     
     
         30 . The tie rod in accordance with  claim 24 , said mid portion comprising a means for non-releasable engagement with a surrounding casting material. 
     
     
         31 . The tie rod in accordance with  claim 24 , further comprising said mid portion and said stem portion surrounded by said mid portion arranged to form a watertight, non-releasable, through plug. 
     
     
         32 . The tie rod in accordance with  claim 24 , said abutment surface comprising a widened cross-section in an end portion of said mid portion. 
     
     
         33 . The tie rod in accordance with  claim 24 , further comprising at least one portion of said mid portion having a non-circular cross section.
