An insulating joint for pipelines comprises two metal tubular parts each having a dilated end portion, the dilated portion of one of the tubular parts being located within the dilated portion of the other tubular part and the dilated portions extending substantially parallel to each other so as to form a gap therebetween, two sleeves composed of an insulating material and forcefully introduced into the gap one after the other in a longitudinal direction so as to form a space therebetween, and a gasket located in the space and forcefully compressed between the two sleeves.
