A pipe coupling includes a first and second connected tubular element forming an elongated tube and being connected by a connection arrangement that biases the first tubular element against the second tubular. An annular sealing element is provided between and overlapping opposed end portions of the elements. The annular sealing element has a generally T-shaped cross-section and includes a first portion that forms a stem of the T-shaped cross section and extends in a radial direction and defines the outer periphery thereof, and a second portion formed by two opposing flanges that form the cross-bar of the T-shaped cross section and define the inner periphery thereof. At least one of the flanges presents a rounded bulge forming an outer peripheral surface of one flange. The bulge is sealed with an inner periphery of one of the tubular elements and extends continuously around the circumference of the annular sealing element.
