ABSTRACT OF THE DISCLOSURE A pipe coupling device, especially suitable for use in cryogenic systems, including a plurality of arcuate collar segments each having a radially extending inner groove with cam surfaces to grasp flanges at the ends of a pair of pipes to be coupled together in a fluid-tight arrangement. The ends of the collar segments are pivotally interconnected into a generally circular configuration having a pair of adjacent unconnected end portions. Means are provided for clamping the end portions of the collar together and for pressing the collar segments against the pipe flanges. A hydraulic jack is provided for forcing the end portions of the collar segments apart and for pivotally moving the collar segments radially outward from the pipe flanges when the pipes are to be disconnected. Flexible protectors about the pivot connections facilitate the break- ing of ice which may form around the coupling device. -1a-
