The invention discloses a flexible sleeve for plain-wall pipes and relates to the field of pipeline fittings. A plurality of V-shaped grooves are formed in the middle of the flexible sleeve, a socket, a rubber ring groove and a lead-in opening are formed in each of two sides of the flexible sleeve, and the flexible sleeve body is made of a low-density polyethylene material and therefore has favorable axial expanding and bending performance. The flexible sleeve is used together with an elastic seal ring to achieve excellent sealing performance, is used for connecting large-diameter plastic drainage plain-wall pipes, is a multifunctional connecting piece, and can not only adapt to axial stretching and shrinking of plastic pipelines due to expansion caused by heat and contraction caused by cold, but also prevent the connecting parts of the pipelines from disengagement or cracks caused by irregular inclination of the pipelines due to local sinking of a foundation, thereby preventing leakage.
