Claim 3:
4. A fastener securely coupling a first body to a second body, comprising:
an elongate arcuate body curved along a longitudinal axis and having a cross-sectional area taken planar normal to the longitudinal axis, the elongate arcuate body comprising a first portion separated along the longitudinal axis from a second portion with the cross-sectional area of the elongate body increasing from the first portion to the second portion, wherein the elongate arcuate body further comprises a first end proximate to the first portion and a second end proximate to the second portion;
a retainer; and
a retaining portion comprising a rod member extending from and pivoted by a proximal end to the elongate arcuate body proximate to the first portion, the retaining portion configured to engage the retainer in a tightening procedure to selectively secure the elongate arcuate body in an inserted configuration where the first body is coupled to the second body, and the retaining portion configured to remain engaged with the retainer in a loosening procedure with the retainer being configured to selectively withdraw the elongate arcuate body from the inserted configuration by a pulling force where the elongate arcuate body is sufficiently retracted by the retainer to permit the second body to decouple from the first body.
