A coupler comprises a male component and a female component including an interior chamber for receiving the male component. A catch extends into the interior chamber for cooperating with the male component to axially secure the male component with respect to the female component. A release comprises a slide located adjacent the catch, whereby depression of a button on the catch causes the catch to resiliently deform and move along the slide to a position free of engagement with the male component. The coupler can be used to attach a holder for holding an auxiliary device to a clamp. The coupler has a first position wherein the holder is spaced a first distance from the clamp and is fixed rotationally relative to the clamp, and a second position wherein the holder is spaced a second distance from the clamp and is free to rotate with respect to the clamp while remaining coupled to the clamp.
