摘要

A self-penetrating fastener for clamping and retaining tubing or the like to a support surface in spaced relationship thereto. A pin member is formed with a recess beneath the head and adjacent the shank of the pin. A flexible channel shaped liner is carried on the shank so that the liner is forced upwardly of the shank, responsive to the driving of the fastener, into and following the contour of the recess to diminish the throat dimension of the recess and substantially surround the tubing received and clamped therein with a single driving impact from a tool.
