A tubular clamping and sealing coupler for underwater oil or gas pipelines or the like operating under high pressure, providing a fluid-tight joint between the sections of the pipelines, one section of the coupler being firmly secured to the pipe on which it is mounted while the other section of the coupler is mounted on the adjacent pipe and is tightened into sealing and clamping position against the first mentioned coupler, a single operation performing the clamping and sealing and coupling function, said coupler eliminating the need for precise alignment of the pipes or use of a chemical sealing compound.
