A pipe coupling 1 for connecting together two pipes in a fluid-tight manner comprising an outer tubular casing 10, an inner tubular casing 20 and a tubular sealing sleeve 30. The sealing sleeve 30 has two sets of inwardly projecting ribs 32, which in use, are pressed into sealing engagement with the respective ends of the pipes. The inner and outer casings are longitudinally split and tensioning screws 17 on outer casing 10 can be tightened to tighten outer casing 10 around inner casing 20 and sealing sleeve 30. Frusto-conical gripping rings 40 grip the pipes by fitting into an annular groove positioned close to the end of said piped in order to secure the pipes against axial displacement. <IMAGE>
