Patent ID: 7867207

Claim:
An ostomy device coupling assembly comprising a first, second and third coupling element for coupling a first and second part to each other in an axial direction, wherein the first coupling element comprises a first engagement area, extending between a first inner radius and a first outer radius, the second coupling element comprises a second engagement area extending between a second inner radius and a second outer radius, the third coupling element comprising a locking member and being axially displaceable in relation to the second coupling element between a locking position and an unlocking position, and wherein the locking member is disposed between the second inner radius and the second outer radius of the second engagement area, the locking member radially displaceable to an engagement position in which the locking member expands the second outer radius to a size larger than the first inner radius and radially displaceable to a disengagement position in which the locking member allows the second outer radius to retract to a size smaller than the first inner radius.
