摘要

The connection (1) has a retention ring (18) encompassing an insertion end of a tube (2) at a circumference of the ring and arranged in an inner groove (12) of a connecting sleeve (4). The sleeve has a slit-shaped wall section (13) around a partial region of a circumference of a cylindrical sleeve segment (11) having the inner groove, through which the retention ring is inserted to produce the connection. A valve housing or a connecting tube and a clamping ring are made of plastic, where a spacer element e.g. ring, and clamping collars are made of metal.
