Abstract
A fastener comprising a male member formed of a flat base, a clipping shank provided on the underside of the base, and a pillar erected upright from the upper side of the base and provided at the leading end thereof with a head, and a female member formed of a tubular part, a pair of depressing blades raised through thin-walled hinges from the tubular part and projected parts provided at the lower ends of the depressing blades. This fastener provides the fastening of a compressible sheet such as an insulator sheet or carpet to an interior decorative panel in an automobile, for example, by having the tubular part set around the pillar of the male member with the depressing blades kept in an upright position, causing the head of the pillar to force the depressing blades down to a level position thereby bringing the projected parts into fast engagement with the underside of the head of the pillar and nipping the compressible sheet fast in position between the male member and the female member.
