ABSTRACT:
A coupling for joining two pipes having end sections, each of which is provided with a circumferential locking rib and can be inserted into the coupling, wherein the coupling has at least one elastic ring that joins at least two elongated webs, and wherein the coupling has stop projections, which lock in place behind the locking ribs when the end sections are inserted in the coupling and can be unlocked to release the connection of the pipes by expanding the at least one ring. Each ring is a separate element from the webs.
