Coupler

A coupler is a device used for holding the decorating tips on the end of a pastry bag. The decorating tips allow you to create different types of designs when decorating. The coupler consists of two sections, the base and the ring. The decorating tips are attached using the coupler. The coupler base is placed inside the bag through the hole at the narrow end of the pastry bag. The decorating tip that is to be used is placed in the coupler ring and then attached to the pastry bag by screwing the ring on to the base. This holds the tip in place but allows the tip to be easily changed when decorating if a different design is needed.
