Abstract: An adjustable attachment device for mounting an accessory, such as a bicycle, ski, or cargo rack, to a frame, such as an automobile roof rack. The device includes an elongate pin rotatably mounted across an aperture in a housing to which one end of a strap is attached, the pin having a shaft about which the strap is wound. A collar having a ratcheted perimeter is coupled to the pin. A capsule, having a cavity therein for receiving the collar, is attached to the housing, the capsule including teeth therein for engaging the ratcheted perimeter of the collar. A tool may be directed through an opening in the capsule into the cavity to direct the collar axially for disengaging the ratcheted perimeter from the teeth and to rotate the collar and pin.
