Coupling arrangement for corrugated metal tube

摘要

The connecting arrangement (1) has a tubular attaching part (3) for attaching a metal corrugated pipe (2) to pipeline units, and a clamping ring (4) for clamping the corrugated pipe. A sealing ring (5) and a coupling ring (6) deeply press the clamping ring. The attaching part and the coupling ring possess thread areas (10, 13, 14). The clamping ring includes an inner sleeve (17) and an outer sleeve (19), which is arranged at a distance to the inner sleeve. A circular recess (20) is formed between the inner sleeve and the outer sleeve for retaining an end (7) of the corrugated pipe.
