In order to simplify the insertion means, the wire piece is pushed into the hole by means of the same wire whereoff the wire piece has been cut. A wire bolting device devel- oped for effecting the method comprises a cutting means mounted on the carrier of the device between a wire feeding mechanism and a resilient guide pipe attached to a head guide. A mounting space is provided beside the cutting means for the mounting of a pushing support be- tween the ends of the cut wire. (Figure 3)
