A pipe boring device (in the form of a self-tapping ferrule strap) comprising a housing 101 having a tubular body 102, 103, with a base (120) for engaging a pipe, a bore (123) extending from the base into the tubular body with a cutter 105 received therein for boring a hole in a pipe, a fluid passageway 128 at least partially surrounding the bore and an outlet for connecting the fluid passageway with a branch pipe, wherein the base comprises one or more transfer passages 126 external of the bore which provide, in use, fluid communication between the fluid passageway and a hole formed in the pipe by the cutter. The one or more transfer passages external of the bore allows for effective extraction of fluid from a pipe to a branch pipe. The transfer passages may therefore be said to bypass the bore. Extraction of fluid is possible almost immediately after the cutter has been retracted from the bored hole. The use of transfer passages external of the bore also eliminates the need for radial holes.
