The insertion connection for a hollow body in the form of a one-piece cutout of flexible material which can be rolled up consists of at least two hooks (H1, H3) in the form of a non-rectangular parallelogram. The hooks are at an angle on one side of between one and 89 degrees, preferably 45 degrees (W1, W6) and on the other side from 91 to 179 degrees, ideally 135 degrees (W2, W5) from the main body (HK). |
