ABSTRACT:
The invention provides a junction coupling for branching a flow of fluid from a pipe or conduit. The junction coupling is essentially C-shaped and is dimensioned partly to surround such pipe or conduit. Opposite limbs of the C-shaped member carry, on the one hand, an outlet duct and on the other hand means for securing the coupling in position on the pipe or conduit. The outlet duct is alignable with an aperture in the conduit wall and adapted to receive a branch conduit. The dimensions of the C-shaped member are such that the coupling may be engaged over the pipe or conduit only at the location of the aperture therein.
