A quick-release coupling seal for two duct pipes which are to be connected to one another axially end-to-end, which seal comprises an elastic sealing ring (1), which forms two sealing lips projecting from a base part (3), and a binding device (2) surrounding the base part, the sealing ring being arranged with its base part to be mounted in an annular track (8) which is formed out in one duct pipe (7). The sealing ring has a V-shaped cross-section and the binding device is in the form of thread. The binding device surrounds the sealing ring loosely such that the sealing ring can be pivoted like a link around the binding device in the annular track of the duct pipe. IMAGE
