摘要

Quick-release coupling (1) for domestic pipelines comprises a tubular inner part (2), an inner sleeve (3), a clamping ring (5), a toothed ring (6) having partially circular teeth (61), and an outer sleeve (4). The outer sleeve has a cylindrical region with at least two different internal diameters (d1, d2, d3) and a conical region receiving the clamping ring. The inner sleeve consists of two almost identical hemispherical shell parts. Preferred Features: The shell parts are provided with an external thread (36) onto which the outer sleeve provided with an internal thread (41) is screwed. The inner sleeve has fingers (37) with finger surfaces pointing radially outward which are designed so that the toothed ring is supported by the fingers and is held at least in the pre-assembly position.
