Abstract
A connection device for a peripherally ribbed pipe (4), including: a pipe receptacle (1) having a receiving opening for receiving an end of the pipe (4); and a catch element (3) for fastening the pipe (4) in the pipe receptacle (1). The pipe receptacle (1) has a longitudinal center plane (M), which extends through the receiving opening. The catch element (3) has a first point (SI), which allows movement of at least part of the catch element relative to the pipe receptacle (1), and a second point (S2), which is designed to engage in a corrugation trough (41) of the peripherally ribbed pipe (4). At least when the pipe (4) is inserted and fastened, the first point (SI) lies closer to the longitudinal center plane (M) than the second point (S2) does. The connection device allows easy, leaktight, and secure fastening of a pipe.
