Patent ID: 7143485

Claim:
A clip comprising a flange larger than a through-hole in an attached member, a shank unitary with the flange and extending from the flange at one end of the shank to a predetermined height along a longitudinal axis of the shank for insertion into the through-hole, a pair of arms extending from an opposite end of the shank and hinged thereto for rotation relative to the shank, and levers extending from bases of respective arms, connected thereto for rotation with the arms, and providing spaces with respect to the arms for receiving portions of a through-hole section of the attached member between the arms and the levers, wherein, the clip is constructed so that in an initial posture of the clip, the arms extend substantially axially of the shank beyond said opposite end of the shank, and the levers extend beyond said opposite end of the shank longitudinally away from the shank and laterally away from the shank to form acute angles with respect to the longitudinal axis of the shank, so that tip portions of the levers are disposed to engage one side of the attached member before the shank is inserted into the through-hole, and wherein the clip is constructed so that when the shank is inserted into the through-hole, the arms rotate together with the levers from the initial posture to an interposed posture at which the portions of the through-hole section of the attached member are received in the spaces, at which the levers are in contact with said one side of the attached member, the arms are substantially parallel to the flange and in contact with an opposite side of the attached member, and the flange is juxtaposed with the one side of the attached member, wherein each arm has an arm-end locking pawl at the base thereof extending towards the flange when the arm is in the interposed posture, and wherein cooperable flange-end locking pawls are formed on the flange to engage the arm-end locking pawls and keep the arms in the interposed posture.
