Abstract (en)
[origin: WO2008000359A1] The invention relates to a fitting assembly unit which comprises a connecting fitting (4) having at least one connecting piece (3) onto which a pipe (2) can be slid. A plastic holding ring (26) projects beyond a compression sleeve (36) in at least some sections and is snap-connected to the connecting piece (3). The plastic holding ring (26) is permanently fixed to the compression sleeve (36) in a position that is defined in the axial direction of the connecting piece (3). Compression pliers having compression cheeks (41) are used to fix the compression sleeve (36). A compression web (43) of the compression pliers (36) is axially directly adjacent to the holding ring (26). An additional compression web (44) extends in the vicinity of a free end (37) of the compression sleeve (36). A third, central compression web (42) extending at the level of an annular groove (17) for a sealing ring (20) has an axial length that has a ratio to an overall compression width of the compression cheek (41) of approximately 1:2.5 to 1:3.5. The invention provides a fitting assembly unit the plastic holding ring (26) of which is prevented from undesired deformations while at the same time allowing the compression sleeve (36) to be securely compressed.
