Pine tree clip

A one-piece fastener for insertion through an aperture in a member and comprising:

• a head;
• a rigid shank extending from said head and terminating in a tip;
• at least a pair of circumferentially spaced-apart rigid ribs extending radially outwardly from and along the length of said shank, each of said ribs having a pair of oppositely facing side walls and an outermost end engageable with a side of said aperture in said member;
• and a plurality of axially spaced-apart flexible flaps extending laterally outwardly from and along the length of said ribs, each flap comprising an inner edge said flap being is integrally attached to said shank and to one of said oppositely facing walls of only one rib and extending radially outwardly beyond the side of said aperture, some of said flaps being disposed on each oppositely facing wall of said ribs and those flaps on one of said oppositely facing side walls of one rib being axially offset from those flaps on the other of said oppositely facing side walls of said one rib, said ribs together forming a sufficiently large cross-sectional width whereby said shank is tightly engaged in said aperture and is thereby maintained in a substantially normal position relative to said member, said flaps being flexible to enable insertion of said fastener into said aperture and returnable to unflexed position thereafter whereby flaps adjacent a surface of said member maintain the fastener in axially immobile position.
