Abstract: A flexible pipe-connecting fitting, particularly for connecting pipe ends located opposite and at an axial distance from one another, includes a tubular connecting member which has a central portion, two transition portions adjoining the central portion, and holding portions each adapted to be installed on a corresponding pipe end. The fitting is further provided with securing elements operative for fixing the holding portions to the corresponding pipe end.

Abstract: A flexible pipe coupling wherein the median section of an elastic hose constitutes a bellows and the conical outer sections of the hose taper outwardly from the respective ends of the bellows and have inwardly extending annular collars remote from the bellows. The outer sections have internal sockets for sealing rings which extend into annular grooves machined into the outer end faces of connecting rings serving to secure the outer sections to the flanges of two spaced-apart pipes. When the connecting rings are bolted to the respective flanges, the collars are deformed between the respective connecting rings and flanges, and the sealing rings penetrate into the adjacent grooves and impart to the corresponding outer sections an S-shaped cross-sectional outline. The hose is reinforced by an insert consisting of several layers of steel cords and being embedded into the elastic material of the hose so that it extends into the collars, into the remaining portions of the outer sections as well as into the bellows.
