A dispensing assembly comprises a syringe and at least one accessory, such as a mixer or a closure cap. The syringe defines a first fastening area with a first pair of retaining elements, and the accessory defines a second fastening area with a second pair of retaining elements. The accessory has a housing with two mutually opposite, compressible housing portions. These housing portions are offset in relation to the second pair of retaining elements along the circumference of the housing. The fastening areas are configured such that the accessory is capable to be slipped-on the syringe and removable therefrom without a twisting motion, by applying pressure to the compressible housing portions.
