Decorating rollers

A decorating roller assembly comprising:

• a retention assembly for a hollow tubular decorating roller comprising:
• a fixed mount member securable in use to a roller frame and including a first primary support formation and a first retention formation extending radially beyond the first primary support formation;
• and
• a separable mount member selectively couplable with the fixed mount member, the separable mount member including a second primary support formation and a second retention formation extending radially beyond the second primary support formation,
• the first and second primary support formations being received, in use, by a respective end of a hollow tubular decorating roller, the first and second retention formations cooperating with one another while the separable mount member is coupled with the fixed mount member to in use retain a hollow tubular decorating roller therebetween,
• wherein each of the first and second primary support formations includes a respective mutually engageable attachment formation, one of the mutually engageable attachment formations is a receivable attachment formation and the other one of mutually engageable attachment formations is an insertable attachment formation, the receivable attachment formation includes an opening and the insertable attachment formation incudes an inserting portion for inserting into the opening of the receivable attachment formation,
• the insertable attachment formation further including a locking member configured to cooperate with the receivable attachment formation when the inserting portion is inserted into the opening to couple the receivable and insertable attachment formations to one another, wherein the locking member includes first and second locking member portions protruding from the insertable attachment formation and being spaced from one another to locate a portion of the receivable attachment formation therebetween, wherein:
• the first and second locking member portions each take the form of a barb portion, each barb portion having a tapered end and a non-tapered end,
• the non-tapered end of each barb portion facing one another, and
• the first and second barb portions locate at either side of the opening of the receivable attachment formation;
• and
• a hollow tubular decorating roller within respective ends of which is received a corresponding first or second primary support formation of the retention assembly.
