Abstract: 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).
