<p>The connection for a subsoil drainage system, connects a small dia. lateral drainpipe (2) into a carrier pipe (1) of a greater dia., and aligns the lateral axis (11) with the longitudinal carrier axis (14). The lateral pipe may have a circumferentially ribbed barrel, its extremity entering a carrier spigot (6) to be secured by a retaining sleeve (8). A locking sleeve (10) may slide onto the sleeve end, and the spigot may be provided by a carrier clip saddle (5). The retaining sleeve may house onto the spigot and reduce (9) to the spigot dia. to enter the locking sleeve (10).</p> |
