  • Manually releasable clip holder
    Patent number: 7117566
    Abstract: A manually releasable clip holder for receiving, securely holding and manually releasing a serpentine clip has a substantially flat base-plate. An insert is coupled to the base-plate. The insert has an insert cover with a top edge that forms an insert channel over the base plate. A channel aperture is formed at the insert cover top edge. A flap is pivotally coupled to the base plate and has a bottom edge. A spring is coupled to provide a restoring force to return the flap to a predetermined restored position with the flap bottom edge positioned above and beyond the insert cover top edge and the channel aperture. The separation between the flap bottom edge in the restored position and the insert cover top edge forms a window to the channel aperture. The flap is displaced toward the base-plate in response to a light deflection force from a serpentine clip.
