Abstract
A two-part fastener intended for securing, e.g., a panel 41 to a frame member 42 comprises a tubular shell 11 and a pin 12. The shell bore contains a tubular insert or slug 14 of resilient nylon material. The exterior of the pin is formed with annular barbs 30. When the pin is inserted into the shell, the barbs 30 engage in the resilient slug 14 to secure the pin and shell together. The pin includes a removable pintail 33 which protrudes beyond the shell and assists in the pulling of the pin into the shell by means of a suitable pulling tool.
