Abstract
The device is provided for a coupling which comprises an annular sealing element interposed and compressed radially between the socket of one pipe element and the male end of the other pipe element. The pipe elements are capable of having an angular deviation therebetween. The device comprises an annular shoulder integral with the male end which shoulder is disposed, in the assembled state of the coupling, between an inner flange at the entrance of the socket and the sealing element. A split ring surrounds the male end between the flange and the shoulder. Screws engaged with and extending through tapped passages arranged circumferentially around and carried by the flange bear against a face of the shoulder so as to apply the ring against the shoulder.
