A clamp arrangement for securing an accessory to an oscillating power tool can include a clamp assembly including a first clamp member that moves relative to the accessory between a closed position wherein the clamp assembly retains the accessory and an open position wherein the first clamp is offset from the accessory permitting removal of the first accessory from the clamp assembly. The clamp assembly can further comprise a second clamp member having a first portion that opposes the first clamp member and cooperates with the first clamp member to clamp the accessory between the first and second clamp members. An attachment plate can carry the clamp assembly. The attachment plate can have a first mating detail formed thereon that is configured to selectively and removably mate with a complementary second mating detail on the power tool in an assembled position.
