A pipe connector device for selectively interconnecting a pair of pipe elements in an end-to-end relationship and for sealing a junction between the elements to prevent leaks. A first and a second pipe element each includes a cavity adjacent to a center bore in the pipe element. The first pipe element has a substantially smooth inner surface which defines an outer boundary of a first cavity. An annular seal mounted in the cavities seal the junction between the pipe elements. A threaded outer portion of the seal has a plurality of radially outer points which press against the inner surface of the first cavity to retain the annular seal in the first cavity when the pipe elements are separated.
