Abstract: Device for drawing conductive cables through a sheath by vacuum applied to one end of the sheath, comprising a body of rotation in the form of a cap having a skirt which ensures pneumatic sealing with the interior of the sheath. An anchor extends axially in one direction from the cap and has an opening therethrough in which the cables can be received. An axle extends forwardly in the other direction from the cap, and there is an enlargement on the end of the axle remote from the cap, by which enlargement the device can be grasped for manually pulling on the assembly of the device and the conductive cables drawn thereby. This enlargement can be spherical, of about the same diameter as the cap and skirt, or else semispherical and of a diameter about half that of the cap and skirt.
