Abstract:
A fastener for maintaining the relative position of concentrically nested inner and outer tubes, the inner tube having an inside surface and an outside surface separated by a first tubing wall thickness, the outer tube having an interior surface and an exterior surface separated by a second tubing wall thickness, and the inner and outer tubes having respective first and second holes penetrating the first and second wall thicknesses, respectively, the fastener comprising:a projection adapted for matingly engaging the first and second holes; a resilient body connected to the projection and adapted to bias the projection through the first and second holes, the resilient body being elastically deformable between a first configuration, where the projection is adapted to extend through the first and second tubing wall thicknesses, and a second configuration, where the projection is adapted to extend through the first tubing wall thickness; and a closure integrally connected to the resilient body and adapted to overlie the first wall thickness, wherein the closure is configured to occlude an end of the inner tube.
