Abstract: This invention relates to a device for the sealed connection of two pipe elements, wherein it comprises in projection on the pipe elements two members capable of being moved towards each other by at least one clamping means and of which the contiguous faces defined opposite grooves for housing a crushable seal comprising an inner toric ring of which the convexity is directed outwardly and an outer toric ring of which the convexity is directed inwardly. According to the invention, the seal is constituted solely by such rings, which abut on each other opposite the annular crests of their convex parts and the circular groove of each connecting member presents convergent bearing surfaces pressing the edges of said rings.
