AbstractA device to facilitate the connection of a relatively small diameter hose to a larger diameter pipe has a tubular plug-like configuration with a flared portion at one end and a cylindrical portion at the other end. With the cylindrical portion placed within the end of the hose, both the device and the hose are inserted through a side opening in the pipe. When inside the pipe the hose is pushed further onto the flared end portion of the device so that the hose is stretched to a diameter larger than the opening. Tension on the hose causes it to lodge tightly in the opening and form a permanent connection.
