Abstract: An apparatus for connecting a first tubular conduit to be in flow communication with a second tubular conduit includes an adapter and a generally cylindrical wedge. The adapter defines an upper, generally cylindrical surface and a lower, generally cylindrical surface with an inner ledge therebetween. The adapter is configured for connection to: (i) the first tubular conduit such that a portion of the adapter is substantially flush with an inner surface of the first tubular conduit, and (ii) the second tubular conduit such that there is flow communication therebetween. The wedge has an outwardly extending flange portion and a generally cylindrical depending portion. The wedge is configured for insertion into the adapter such that the flange portion abuts against the ledge of the adapter and the cylindrical portion is substantially flush with the inner surface of the first tubular conduit.
