Abstract: The socket of one of the pipe elements has on at least a part of its outer end a radial abutment defining an abutment face facing inwardly of the socket. A device for locking the joint against forces tending to separate the pipe elements comprises at least one locking member having the general shape of a sector of a cylindrical ring and defining an inner wall which is secured to the smooth end portion of the other pipe element. At least one projecting portion is provided on the locking member and bears axially against the abutment face.
