A fastening device is disclosed for attachment to a pole without the need for tools and without the need for excessive force to mount or remove the device from the pole. The device has an interior channel that is open along a side of the fastening device. The opening in the channel along the side of the device is defined by first edges that are uniformly spaced apart and contiguous second edges that are angled away from each other, starting with the spacing of the first edges, until their spacing is equal to the diameter of the pole. To mount the fastening device to the pole its top edge with the widest spacing of the second edges are placed against the pole and pushed on to the pole for a short distance before rotating the bottom of the fastening device on to the pole. This attachment sequence distributes the mounting force timewise making it easier to attach or remove the fastening device to or from the pole.

What is claimed is: 1. A device for fastening items to a pole, the fastening device comprising: a main body; a first, elongated arcuate member attached to the main body, the first arcuate member having lengthwise contiguous first and second edge portions furthest from the main body; and a second, elongated arcuate member attached to the main body, the second arcuate member having lengthwise contiguous third and fourth edge portions furthest from the main body; wherein the first, elongated arcuate member and the second, elongated arcuate member define an elongated open channel between them; wherein the first and second edge portions do not touch the third and fourth edge portions and the space between them leaves the channel open; wherein the first and third edge portions are generally parallel and the second and fourth edge portions diverge apart starting at a point where they are lengthwise contiguous with the first and third edge portions, and the spacing between the second and fourth edge portions is wider further away from the contiguous point; and wherein the first and second elongated arcuate members are resilient and can be readily spread apart to attach the device to the pole, wherein the second and fourth edge portions initially contact the pole and spread apart followed by the first and third edge portions contacting the pole and spreading apart as the device is attached to the pole, and the first through fourth edge portions then return to their original positions to hold the device to the pole. 2. The device for fastening items to a pole in accordance with claim 1 further comprising means for attaching items to the device after the device has been fastened to the pole. 3. The device for fastening items to a pole in accordance with claim 2 wherein when the device is being attached to the pole, the pole initially lies between the second and fourth edge portions where they are spaced the furthest apart, and the pole lies partially in the open channel so that it is retained in the channel and does not slip therefrom as the pole is fully entering the channel to be mounted on the pole. 4. The device for fastening items to a pole in accordance with claim 3 wherein as the device is being attached to the pole, the pole progressively passes between the second and fourth edge portions and the first and third edge portions in a timewise manner to minimize force necessary to attach the device to the pole. 5. The device for fastening items to a pole in accordance with claim 1 wherein as the device is being attached to the pole, the pole progressively passes between the second and fourth edge portions and the first and third edge portions in a timewise manner to minimize force necessary to attach the device to the pole. 6. The device for fastening items to a pole in accordance with claim 5 wherein when the device is being attached to the pole, the pole initially lies between the second and fourth edge portions where they are spaced the furthest apart, and the pole lies partially in the open channel so that it is retained in the channel and does not slip therefrom as the pole is fully entering the channel to be mounted on the pole. 7. The device for fastening items to a pole in accordance with claim 5 wherein the spacing between the second and fourth edge portions at the last mentioned point equals the width of the pole. 8. The device for fastening items to a pole in accordance with claim 1 wherein when the device is being attached to the pole, the pole initially lies between the second and fourth edge portions where they are spaced the furthest apart, and the pole lies partially in the open channel so that it is retained in the channel and does not slip therefrom as the pole is fully entering the channel to be mounted on the pole. 9. The device for fastening items to a pole in accordance with claim 8 wherein as the device is being attached to the pole, the pole progressively passes between the second and fourth edge portions and the first and third edge portions in a timewise manner to minimize force necessary to attach the device to the pole. 10. The device for fastening items to a pole in accordance with claim 8 wherein the spacing between the second and fourth edge portions at the last mentioned point equals the width of the pole. 11. A device for fastening items to a pole, the device comprising: a body having a side with a recessed elongated channel within and along the length of the side of the body, the channel not being fully inside the body so that it defines an elongated opening having a first side and a second side on opposing sides of the elongated opening and along the length of the side of the body, and the elongated opening provides an entrance for the pole to enter the recessed channel, the first side of the opening is defined by a portion of the body defining first and second edge portions that are lengthwise contiguous to each other and the second side of the opening is defined by a portion of the body defining third and fourth edge portions that are lengthwise contiguous to each other; wherein the first and third edge portions are generally parallel and the second and fourth edge portions diverge apart starting at the point where they are lengthwise contiguous with the first and third edge portions, and the spacing between the second and fourth edge portions is wider further away from the last mentioned point; and wherein the first and second sides are resilient and can be readily spread apart to attach the device to the pole, wherein the second and fourth edge portions initially contact the pole and spread apart followed by the first and third edge portions contacting the pole and spreading apart as the device is attached to the pole, and the first through fourth edge portions then return to their original positions to hold the device to the pole. 12. The device for fastening items to a pole in accordance with claim 11 wherein as the device is being attached to the pole, the pole progressively passes between the second and fourth edge portions and the first and third edge portions in a timewise manner to minimize force necessary to attach the device to the pole. 13. The device for fastening items to a pole in accordance with claim 12 wherein when the device is being attached to the pole, the pole initially lies between the second and fourth edge portions where they are spaced the furthest apart, and the pole lies partially in the open channel so that it is retained in the channel and does not slip therefrom as the pole is fully entering the channel to be mounted on the pole. 14. The device for fastening items to a pole in accordance with claim 13 further comprising means for attaching items to the device after the device has been fastened to the pole. 15. The device for fastening items to a pole in accordance with claim 11 further comprising means for attaching items to the device after the device has been fastened to the pole. 16. The device for fastening items to a pole in accordance with claim 15 wherein when the device is being attached to the pole, the pole initially lies between the second and fourth edge portions where they are spaced the furthest apart, and the pole lies partially in the open channel so that it is retained in the channel and does not slip therefrom as the pole is fully entering the channel to be mounted on the pole.
