Abstract: The apparatus enables a saddle-shaped parallel connection tapping to be installed on a pipe from the top of a hole in the ground. The apparatus comprises a frame having a tipping thrust device in the form of a spade controlled by rodding and designed to take up a position beneath the pipe, and a removable tapping positioner guided in the frame and including a tubular column that is split along one of its generator lines and that is fitted at its bottom end with a disconnectable module engaging the rims of the tapping. Means are provided on the frame to exert downwards pressure on the tapping support module in selective manner, and the removable module includes means for welding the tapping to the pipe. A device for driving a plug or a perforator device can be inserted in the cylindrical column of the tapping positioner from above.
