The present invention relates to a pipe fitting that can be applied to agriculture and fishery, which is a hollow tubular structure mainly consisting of a plurality of ribs protruding radially from the inner tube wall of a pipe body toward the central axis. The rib reinforcement strengthens the structural strength of the pipe, but the pipe member retains the original flexible characteristic of the bendable recovery, and the rib can also be pressed against the outer wall of the pipe having a smaller diameter which is placed in the pipe diameter of the pipe body. The positioning is to improve the structural strength of the overall pipe fitting, and even the plurality of pipe fittings are connected in series through the connecting member into a desired embodiment； thereby improving the applicability of the pipe fitting and its economic benefits.本創作係有關於一種能應用於農、漁業的管件，其係為一中空管狀之結構體，主要係在一管體的內管壁往中心軸呈徑向凸伸複數個凸肋，藉由凸肋補強管件結構強度，卻又能使管件保留原有的可彎曲回復之撓性特色，同時凸肋還能與穿置於管體管徑內之另一管徑較小之管件的外壁緊迫抵觸定位以提升整體管件的結構強度，甚至透過銜接件將複數根管件串接成所需實施的態樣；藉此，提升管件的適用性及其經濟效益。
