A piercing grommet which pierces an insulation blanket. A snap-on retainer slides over a spiked portion of the piercing grommet and snaps in place adjacent the bottom of the spike. The spike can then be removed. A seal is created by contact adhesive between the insulation blanket and the grommet in order to prevent moisture ingress.
