An attachment device is provided to attach a distribution device, such as a pump or a valve, onto a neck of a recipient. The attachment device comprises a ring forming a skirt equipped with an attachment structure, such as clip-on heads, designed to co-operate with the neck of the recipient. A reception structure is provided to receive the distribution device. An annular plate extends radially inwards from the skirt. The plate is designed to be pressed against the upper end of the neck, with an inserted seal if required. The plate can be moved axially upwards away from the attachment structure by pressing the plate on the upper end of the neck. |
