The application relates to a drip chamber (1) for an infusion device, to an infusion device with a drip chamber, and to an arrangement composed of an infusion container (16) and of such an infusion device. The drip chamber (1) of the infusion device has a securing part (11) for securing the drip chamber releasably to the infusion container. The securing part (11) of the drip chamber has a plurality of securing elements (12) which are arranged along the circumference of a circle and which, on the inner sides facing each other, have grooves (12A) extending along the circumference of a circle. The securing elements are designed in such a way that they can be spread from a position in which they engage firmly around the connector part of the infusion container to a position in which they release the connector part of the infusion device. The securing elements (12) secure the piercing spike (10) of the drip chamber against slipping out of the piercing part (23) of the connector part (20) of the infusion container.
