The fastening area of the syringe and the fastening areas of the accessories are configured such that the accessories are capable to be slipped-on the syringe and removable therefrom without a twisting motion by applying pressure to their fastening area, retaining means on one part cooperating with retaining means on the other part. To this end, the fastening area of the syringe is provided on opposed lateral portions to which pressure is not intended to be applied with at least a first pair of retaining elements, and these retaining elements cooperate with a corresponding first pair of retaining elements on the accessories. In further developments, the fastening area may comprise two pairs of retaining means and the containers of the syringe may be attachable to one another. Such dispensing assemblies are more cost-effective to produce and simpler to handle. ## Claims ### Claim at position 1 1-21.
