ABSTRACT:
A plastic fastener for pushing axially onto a headed or threaded stud has a hollow shank, part of the wall of which is constituted by a flexible resilient finger. The finger has a deep step for latching under the head of the T-stud and opposite it is a window in the wall of the shank, the floor of the window forming a corresponding step to latch under the other side of the stud shoulder.
The fastener provides greater resistance to pull-off than has usually been found in fasteners having closed ended hollow shanks.
