Patent ID: 7438496

Claim:
A securing apparatus, including a releasing tool, that is only unlocked by rotation of the releasing tool within a release aperture in a deformable body of the securing apparatus and is locked at all other times, comprising: the deformable body having a longitudinal axis, a first aperture centered on said axis configured to provide a secure interference fit with at least one article to which it is fitted, a bore centered on said axis configured for receiving a shaft, and at least one stress reduction slot that is substantially perpendicular to the first aperture and bore, the release aperture having an axis parallel to the first axis, wherein the release aperture having an arcuate section comprising two opposing concave portions centered on two different points of curvature and bisected by a slot perpendicular to the release aperture, the releasing tool having a camming shaft complementary to the shape of the release aperture such that insertion and rotation of the shaft of the releasing tool within the release aperture will cause the release aperture to spread to a point where the required widening of an area of the release aperture is achieved to unlock the deformable body.
