A fastener includes a pin and an assembly that is releasably attachable to the pin and rotatable thereabout. In use, the pin is affixed to the casing of a camera or the like with a portion of the pin projecting therefrom to define the axis of rotation. The assembly includes a ring to which a hanging strap is attachable for supporting the casing. With the assembly attached to the pin, two axially spaced-apart circular flanges on the projecting portion are each journaled in a respective one of two aligned holes in two similarly spaced-apart cover plates of the assembly. To facilitate attachment and release of the assembly when desired, the assembly includes slidable retaining means which is secured between the plates and movable between two positions that respectively retain the assembly in rotatable engagement and release it for easy removal. |
