ABSTRACT:
The invention relates to a device for connecting two pipe ends, having a socket, a spigot and an annular seal therebetween. These parts are clamped together by flanges of a clamp in order to close the device. While prior art sockets and spigots have been made of massive material and shaped by expensive machining processes, the invention provides the spigot which is formed as a generally U-shaped profiled ring having a front and a rear annular flange and holding the sealing element between the flanges. The outside diameter of the front flange is smaller than that of the rear flange. The socket may also be a profiled ring in order to further reduce the manufacturing costs.
