A device for non-rigid connection of two rigid cylindrical pipes comprises the combined use of flexible double-lipped gaskets and toroid flexible gaskets surrounding a bulb-shaped zone formed in one of the pipes. The device is particularly useful for fastening fragile tubes containing light emitters to metal reactors used for photochemical processes.
