ABSTRACT:
A pulling element is provided for use in installing, by means of compressed area, cables in a ducting system including ducts having different inner diameters. The pulling element includes a first part having a first end which is connectable to a cable and a second end which includes a coupling member, wherein first flexible members are provided around a body of the first part for sealing engagement with an inner wall of a first duct having a first inner diameter. The pulling element also includes a second part having a central longitudinal opening and a coupling element capable of cooperating with the coupling member of the first part so as to actively couple the first and second parts when the first part is proximal to the second part, wherein second flexible members are provided around a body of the second part for engagement with an inner wall of a second duct having a second inner diameter greater than the first inner diameter.
