Abstract

This specification discloses a coupling device which is capable of being inserted into an opening of a pipe to form a branch point in the pipe. The device allows for the use of an inexpensive gasketing system and the device is configured such that it will not significantly impede the flow of liquid to the branch point or allow rotation or turning in the opening of the pipe.
