A retention assembly (10) for a hollow tubular decorating roller (202) comprising a fixed mount member (12) that is securable in use to a roller frame (26). The fixed mount member (12) includes a first primary support formation (16) and a first retention formation (18) that extends radially beyond the first primary support formation (16). The retention assembly (10) also includes a separable mount member (14) that is selectively couplable with the fixed mount member (12). The separable mount member (14) includes a second primary support formation (20) and a second retention formation (22) that extends radially beyond the second primary support formation (20). The first and second primary support formations (16, 20) are received, in use, by a respective end (204a, 204b) of a hollow tubular decorating roller (202). The first and second retention formations (18, 22) cooperate with one another while the separable mount member (14) is coupled with the fixed mount member (12) to in use retain a hollow tubular decorating roller (202) therebetween.
