Abstract
According to the present invention, there is provided a plaque holding clip which is characterized by that it has a pair of elastic legs that constitute a trunk of the clip. Because the outer peripheries of the elastic legs are subjected to evenly applied external force and hence smooth changes of load when the clip is introduced into a fitting bore, it maintains its original plaque holding potential for a long time. Moreover, since the outer peripheries of the elastic legs are so designed that they suitably adapt themselves to the inner periphery of a fitting bore, they are free from any undesirable deformations and consequently any changes of the load applied thereto even if the clip is introduced into a fitting bore in an inclined condition. This feature contributes to the ease of handling the clip. A clip according to the invention may be provided with a central pillar to enhance its durability and the ease of handling without deteriorating the other features of the clip.
