Improved plug that is characterized essentially because it is constituted by a generally cylindrical body, superiorly topped in a discoidal expansion of considerable thickness and irregular edge to facilitate its grip without slip, whose cylindrical body comprises a helical rib of great pitch that begins at its lower end and it ends before reaching the mentioned discoidal expansion, the formation taking place, between the termination of the helix and the discoidal expansion, of an annular projection, approximately toric, on which sits an elastic joint of laminar constitution, closed on itself.
