Claim:
A drainage container for collecting body fluids extracted by suction, with a fastening device for fastening the drainage container to a rail so that the drainage container is suspended from the rail, wherein the drainage container has: a rigid outer container, a lid sealingly closing the outer container, and a drainage bag for receiving the body fluids, wherein the fastening device comprises a fastening clamp with a basic body, the basic body having a push-button on one side, a spring-loaded movable claw connected to the push-button, and a fixed claw, the spring-loaded movable claw and the fixed claw forming a slot for receiving the rail, wherein the push-button can be pressed in one direction to move the spring-loaded movable claw in the same direction, wherein moving the spring-loaded movable claw releases the rail, wherein the fastening device further has a connection comprising a slot and a slot pin, the slot being arranged on an opposite side of the basic body and the slot pin being arranged on the outer container or vice versa, wherein the fastening device further comprises a snap lock, a part of the snap lock being arranged on the outer container, the snap lock comprising a leaf spring having a projecting nose, wherein the projecting nose is arranged at a lower end of the connection and engages behind a lower edge of the slot or of the slot pin, and wherein the leaf spring protrudes beyond the lower end of the basic body in the fastened state, wherein the drainage bag can be attached or is attached to the lid in such a way that the lid can be removed from the outer container along with the attached drainage bag by a user releasing and lifting the lid from the outer container, and wherein the snap lock holds the outer container fastened to the rail when the lid with the drainage bag is removed, enabling the user to separate the lid and the drainage bag from the outer container with one hand after a drainage is performed; and wherein the leaf spring can be pressed manually to allow the slot pin to be drawn back out of the slot, thereby releasing the outer container from the fastening clamp.
