ABSTRACT:
A device for attaching an article, such as an armrest, a hand grip, etc., to a base surface is disclosed. The device comprises an attachment clip and an insert which is receivable in an aperture in the clip. The clip is secured in an opening in the base surface. A dentate structure is provided either on the insert or in the attachment clip, and a locking device is provided on the other of the insert or the clip to engage the dentate structure, thereby to secure the attachment clip and the insert together. The locking device preferably is a suitably shaped spring. The insert is either tubular in shape, or a longitudinal segment of a tube. Rotation of the insert to one orientation disengages the dentate structure and the locking device, enabling insertion and removal of the insert. Rotation of the insert to another orientation engages the dentate structure and the locking device for locking the insert against longitudinal shifting.
