ABSTRACT:
A fastener having five parts. A flexible material such as canvas is apertured at a point of connection and a first washer having a boss axially receives the apertures so that the material overlies the washer. The material is held in sandwiched relation between the first washer and a second washer, both of which having gripping surfaces that engage the material. The washers are pressed downwardly by a knob. The knob has a depending central post that releasably engages a lock member that is in turn releasably engaged by a base member that is secured to a support surface. The lock member has a boss part with an annular step that supports the first washer. A pair of flanges extend from a bottom end of the lock member and are engaged by overhanging walls formed in the base member when the knob is turned. The flanges are arcuate so that they resist flattening when the knob is pressed downwardly, and the resistance pushes the washer members upwardly against the downward pushing of the knob, thereby tightly squeezing the material captured between the washer members.
