A fastener comprising two similar releasably engagable parts that may be cut from the same extrusion. Each part has a base portion that may be secured to other objects, and major and minor portions projecting in spaced relationship from the base portion. The major projecting portion has a ridge along its distal end, a recess along its side opposite the minor projecting portion, and a plurality of corrugations facing the base portion along its side surface adjacent the minor projecting portion, and the minor projecting portion has a lip along its side adjacent the major projecting portion. The major and minor projecting portions define slots there between adapted so that the slot on each part can simultaneously receive the ridge on the other of the parts with the corrugations of the parts in face to face relationship and the lips on each of the parts in the slot of the other, to which position the parts may be pressed, and at which position the parts will be retained. |
