Abstract
A pipe coupling includes two sealing rings, each corresponding to one of the pipes. A sleeve is disposed within a retention device. The sleeve has axial end portions, each of which rests against one face of the sealing rings. The retention device has inwardly open grooves, one side wall of which rests against the respective axially inner sides of the axial end portions of the sleeve. The other side wall of the inwardly open grooves exerts an axial force on the other faces of the sealing rings as the clip is clamped, thereby pressing the sealing rings against the pipes.
