A connection assembly for pipes is provided. The assembly includes a pipe, a corrugated conduit, a circumferentially expandable and contractable seal positioned between portions of the conduit and the pipe and a clamp encircling the conduit, seal and pipe. The seal is circumferentially contractible to secure the conduit and the pipe together with the seal serving to effect a gas-tight seal while filling the annular gap between the conduit and pipe. Additional embodiments provide flared sleeves on the corrugated conduit and stops for limiting movement of the components.
