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). When the housing (4) is narrowed and closed and the packing collar (5) is clamped, the clamping ring (13) lies on the corresponding pipe (1 or 2) of the piping. The inwardly inclined front side (11) may be substantially designed as an inner cone (12) and the clamping ring (13) may have a rounded inner edge (20).
