Clips and clip devices are described that can allow a user to at least temporarily attach a loose article to a binding mechanism, for example, a substantially cylindrical binding mechanism. Methods of using these devices are also described.

A binding apparatus including a plurality of generally coaxially arranged binding coils. Each binding coil includes a pair of generally parallel wires terminating in a tip. Each binding coil is coupled to an adjacent binding coil by a connection portion extending generally parallel to an axis of the binding apparatus. At least one binding coil is directly circumferentially attached to itself, or to a connection portion.

A loose-leaf binder comprises a back and a loose-leaf coil. The back comprises a lower sheet and an upper sheet. Each side of the back is formed with a track having a downward opening. At least one end of the back is formed with an open end portion. Each lateral side edge of the lower sheet is formed with a slightly upwardly projecting flange. The lower sheet is formed with at least one engaging slot corresponding to the open end portion of the flange. The loose-leaf coil to be selectively disposed below the back is formed with continuous C-shaped portions by bending a wire. Each end of each C-shaped portion is formed with a track section to slide in the track of the back. The track section can be selectively engaged and restricted within the engaging slot of the lower sheet of the back.

A loose-leaf binder device comprises a back, two end plugs that can selectively close two ends of the back, and a loose-leaf coil for binding inner pages and selectively disposed below the back. The back is formed with an insert slot. A retaining hole communicating with the insert slot is formed on a portion of the back abutting upon an end edge. The end plug is integrally formed with a resilient member to be inserted into the insert slot. A top surface of the resilient member is formed with one post corresponding to the retaining hole of the back. A free end of the resilient member is formed with an upward compressing edge. Thus, the post on the resilient member can be actuated through a compressing edge according to the resilient member of the end plug so that the post is selectively engaged with or disengaged from the back.
