Fastener for plastic structure

摘要

A fastener for a plastic structure includes an elastic hook protrusion formed one of a fixing structure and a coupling structure integrally coupled to the fixing structure and having an extension portion maintaining a width of a profile extended than that of a body portion and a cut portion formed at a center of the extension portion in a lengthwise direction of the body portion, a one-way insertion portion formed on the other structure of the fixing structure and the coupling structure on which the elastic hook protrusion is not formed, having an inclined portion inclined in an elastic pipe form in a direction in which the elastic hook protrusion is inserted and a through hole formed in the coupling structure so that the elastic hook protrusion is inserted and hooked therein, and a wedge inserted in the cut groove of the elastic hook protrusion after the elastic hook protrusion is inserted in the one-way insertion portion to prevent the elastic hook protrusion from being separated from the one-way insertion portion.
