A quick release coupling device for securing end flanges of two adjacent pipes includes a clamp assembly. The clamp assembly has a plurality of clamping members disposed to straddle the two end flanges therearound so as to generally circumscribes the two end flanges. Each clamping member either has a spring or is of spring nature for resiliently urging the clamping member radially outwardly of the end flanges. The clamp assembly also has a plurality of connecting members for connecting respective adjacent pairs of clamping members so as to form an annulus provided a gap between two end clamping members. Coupling means is disposed in the gap for releasably connecting one end clamping member and the other end clamping member against the bias of the clamping members so as to complete the annulus.
