摘要

The device has a plastics cap (3) with a cover plate (4) that fits in the pipe end, a collar (5) with three clamp elements to seal the cover plate and lie against the inner wall of the pipe, and an outer sealing flange (6). The clamping elements form a sleeve-like centring segment (7), which projects at least out over the collar and has at least one elastically deforming locking nose (8a,b) spaced from the flange in its outer area.
