ABSTRACT:
A device for securing a sleeve on the abutting ends of two axially aligned reinforcing bars includes an upper device part, a lower device part aligned below the upper device part and a drawing die mounted on the lower device part. Cylinder-piston units interconnect the upper and lower device parts for moving the drawing die over the sleeve and coupling the reinforcing bars together. The cylinder-piston units are disposed in parallel relation to one another and to the axis of the drawing die. At least one cylinder-piston unit provides the drawing force and another provides a counteracting force. The cylinder-piston units are both located on the same side of the drawing device axis and are spaced at different distances from the drawing die axis.
