Sleeve for joining pipes for friction coupling characterized in that it is constituted by a tubular fragment of a plastic material of the same nature as the pipes to be joined, which has an internal diameter equal to the external diameter of the referred ones tubes and in which parallel circular grooves have been made, arranged in the central area of the sleeve, of which the center has greater depth than the contiguous ones and produces on the internal surface of the sleeve, a more pronounced projection that determines each edge of the sleeve. Stop to limit the introduction of the pipes to be joined, which face each other and are separated from each other by the width of the central slit, while the other slits, marked on both sides, establish a strong friction with the plugged portions of both tubes, whose friction ensures the coupling through the splice sleeve.
