A buckle having a male buckle member and a female buckle member adapted for mating latching engagement with one another, and a removable integrated attachment member adapted to engage with the male buckle member and fits between the male buckle member and the female buckle member when the two are in latched engagement and can be readily and easily removed from the male buckle member. The removable integrated attachment member has a projection that sits above the surface of the buckle members to facilitate attachment of a split-ring, carabiner, s-clip or other device for use in attaching items to the removable integrated attachment member. The buckle is particularly suited for use on an animal restraint, such as a collar or harness, but can also be employed on other articles having buckles anywhere an attachment point is desired.
