Abstract: A pipe coupling has an elastomer packing collar (5) arranged in a closable housing (4) with radial end walls (14) and comprising two axially spaced apart ring-shaped beads (6) which project radially inwards and sealingly lie against a pipe (1, 2). Each ring-shaped bead (6) subdivided into two adjacent radial beads (8, 9) by a ring-shaped gap (7) oriented at an acute angle to the longitudinal axis of the pipe coupling. This gap (7) forms at the outer radial bead (9) a sharp-cornered packing lip (10). The ring-shaped gap (7) may be closed by pressing together and elastically deforming the two adjacent radial beads (8, 9). Each front side (11) of the packing collar (5) is inclined inwards towards the longitudinal axis of the pipe coupling. A conical clamping ring (13) with a subdivided circumference, axially and radially supported on the housing (4), lies against the front side (11) of the packing collar (5).

Abstract: A sealing arrangement for sealing a conduit for a gaseous or liquid agent includes a closable housing which fits sleeve-like around the conduit. A sealing member comprising elastomer material is arranged in the housing in an annular configuration therein and has an annular bead which projects towards the wall of the conduit. The bead has a sealing surface to be applied against the wall. The sealing member has an annular gap which subdivides the annular bead in the axial direction of the arrangement into a first radial bead portion at the inward side of the seal and a second radial bead portion at the outward side of the seal. The gap extends from the sealing surface into the annular bead at such an inclination that an acute-angled sealing lip is formed on the second bead portion adjoining the gap.
