A sealing ring for sealing the connection of a spigot of a corrugated pi pe with a pipe socket has inner beads and lip seals bearing against flanges. Said sealing ring further has an outwardly projecting sealing bead having a central annular bead and two annular collars projecting laterally outward. When said pipe socket is pushed onto said spigot, said sealing bead is rolled in in such a manner that said central annular bead and one annular collar bear against said inside wall of said socket in a sealing-tight fashion.
