The branch connection has a drill (10) allowing formation of a branch hole on the pipe by its movement. It also has a fixing (4,8) for the connection on the pipe. The fixing is disposed to come into contact with the tube by its movement. The drill can be formed by a ferrule (1) carrying the drill and the fixing. A positioning tool (70) can have an end face (73) which comes into contact with the fixing. The drill can be self-cutting and have flutes (10). |
