Discharge arrangement having a connecting device between a multi-component cartridge and an accessory part

The invention relates to a discharge arrangement, comprising a two-component cartridge (2) and an accessory part, for example, a mixer (3). A connecting component (11, 12) of a connecting device is arranged on each of the two parts. In order to make it easier and simpler to attach the accessory part to and remove the accessory part from the cartridge, one connecting component (11, 12) comprises an insertion receptacle (20, 21) and the other connecting component (12, 11) comprises a connection part (5) that can be inserted therein in the longitudinal direction, wherein mutually corresponding engagement parts (6, 7, 25, 26) of a rotational guide placed at an incline in the longitudinal direction are provided on the inner circumference in the insertion receptacle (20, 21) and on the outer circumference on the connection part (5), along which rotational guide the connecting components (11, 12) can be rotated in one another over an effective connecting section after being inserted into one another and thus can be brought increasingly in or out of engagement with each other.
