ABSTRACT:
An attachment apparatus is provided for attaching an elongated shaft to a structural element, wherein the shaft defines a longitudinal axis, and the structural element includes an opening through the structural element which defines a central axis extending in a direction generally perpendicular to the axis of the shaft. The apparatus includes a helical coil of wire having a central coiled section and opposed end sections protruding from the coiled section, an inner space defined by the coiled section that is sized to grip the shaft and to prevent relative axial movement between the helical coil and the shaft when the coil is mounted on the shaft, and a fastening assembly for fastening the apparatus to the structural element when at least one end section is inserted into the opening. The apparatus is mounted on the elongated shaft by rotating the opposed end sections so that the coiled section unwinds, increasing the diameter of the inner space to a point where it is slightly larger than the cross-sectional diameter of the shaft. The elongated shaft is inserted through the inner space to a desired position relative to the apparatus, and the opposed end sections are rotated so that the coiled section rewinds, decreasing the diameter of the inner space until the shaft is firmly retained through the apparatus. In a preferred embodiment, the fastening assembly includes hook-shaped tips defined by the opposed end sections, and spaced-apart by a distance greater than the diameter of the opening.
