Abstract

The invention relates to screwed connections, at least one element of which is formed from a plastic. According to the invention, one of the two elements which rotate with respect to one another has an annular cavity 20 whose size decreases progressively towards the inside, and the other element 12 has a projection 23 whose size decreases progressively towards the outside, but which has an apex angle less than that of the cavity. The connection may be sealed simply by tightening by hand. Application to the connection of pipelines.
