ABSTRACT:
A coupling in which a male end of a pipe element is inserted in the socket of a second pipe element and the axes of the pipe elements may have an angular deviation therebetween. An abutment projection on the male end is axially supported by an inner shoulder on the socket through a ring, bearing against the projection on the side of the latter adjacent the shoulder, and a mass of hardenable material disposed around the projection and the ring between the sealing element of the coupling and the shoulder.
In the case where the shoulder of the socket defines a large radial clearance between itself and the male end, an intermediate tensile locking means is interposed, in the axial direction, between the hardenable material and the shoulder and, in the radial direction, between the male end and the socket, the outside diameter of this means having, with respect to the inside diameter of the socket, axially inwardly of the shoulder, sufficient clearance to allow the angular deviations of the pipe elements.
