The improvements consist of a double flange constituted by two anchoring elements -8- and -8a- and a central watertight joining flange -9-, which are anchored to the outer surface of the ends of the polyethylene pipes to be spliced -6- and - 7-, thanks to the action of projections with a truncated cone-shaped profile -11- disposed on an inner clasp -10-, which on being pressed are driven into the outer face of the ends of both pipes, said improvements being characterised in that they envisage the incorporation of an internal lock ring, consisting of a rectangular stainless steel sheet -1-, being incomplete in the area where an expansion device with which it is equipped is disposed, the ring of which is disposed in the interior of the ends of each of the pipes -6- and -7- to be spliced and disposed underneath the anchoring elements -8- and -8a-- and conveniently adjusted against the inner surface of the corresponding pipe, eliminating the possibility of deformation thereof on being the compensating element of the pressure exerted externally by the projections -11- that are driven into the exterior of each pipe, avoiding the deformation thereof. Said improvements also envisage the existence of projecting fixing screws -13- which are positioned against the inner face of the respective pipe, preventing displacement o the aforementioned rectangular sheet -1-.
