ABSTRACT:
The connection device (101, 201) according to the invention has a locking head (109, 209) that can be locked to an opening (8) of a container wall (3). A clamping device (123, 223) is also provided on the corresponding coupling piece (5), which serves to tighten the head (109, 209) locked to the container wall (3) without a rotational movement against the container wall (3). The clamping device (123, 223) can be designed as a wedge-clamping device (142, 242). The latter permits generation of large clamping forces with small operating forces. The clamping device (142, 242) is preferably secured by a locking device (253), so that vibration-proof connection resistant to temperature changes is achieved during simple assembly.
