Coupling for pipes, in particular for pipes of synthetic materials, comprising a body 1 through which a passage (5) extends, whereof one part is tapped at (12), a nut 2, through which a passage (18) also extends, comprising a hexagonal terminal flange 30 and an external screw-thread (32) adapted for being screwed into the tap (12) of the body 1 and a metal ring 3 which is able to be deformed radially inwards. Before fitting the coupling, the ring 3 is trapped by one of its ends by the nut 2 in order to form a nut-ring arrangement 2-3 which is screwed into the body 1. <IMAGE> |
