  • Members 28A and 28B are disposed on ends of the legs 18A and 18B opposite to the junctures 24A and 24B to facilitate connection of the connector 10, and thereby the article 12, with the support 14.

  • the first surfaces 30A and 30B are inclined to facilitate progressively increasing force application to the fingers 38A and 38B, and thereby correspondingly progressively increasing reduction in dimensions of the slots 34A and 34B, responsive to movement of the connector 10 with respect to the article 12 and/or the support 14. Accordingly, the ends 36A and 36B of the legs 18A and 18B are able to pass through a port on the article 12 or the support 14 having an inner diameter less than an outer diameter defined by the first surfaces 30A and 3OB when the fingers 38A and 38B are in the first position.
  • the connector 10 is inserted through ports (not shown) on the article 12. Specifically, with the fingers 38A and 38B in a first, at-rest position, the first surfaces 30A and 30B of the members 28A and 28B, respectively, engage entering end inner surfaces of ports (not shown) on the article 12.

  • the inclined nature of the first surfaces 30A and 30B facilitates force application to the legs 18A and 18B and guides the legs 18A and 18B into the ports in the article 12. Responsive to that force application, the fingers 38A and 38B flex towards each other (move toward the second position) , thereby reducing dimensions of the slots 34A and 34B. Reduction of slot 34A and 34B dimensions produces a reduced profile of the ends 36A and 36B of the legs 18A and 18B. The reduced profile of the ends 36A and 36B allows the ends 36A and 36B to pass through the ports in the article 12.
  • the legs 18A and 18B are positioned within the ports on the article 12 such that the ends 36A and 36B and the members 28A and 28B are located adjacent a side of the article 12 opposite to a side thereof which is adjacent the surface 26 of the base 16.
  • the legs 18A and 18B may be positioned within the ports in the suppoort 14 in a manner substantially similar to the manner discussed above with respect to positioning of the legs 18A and 18B within ports in the article 12.
  • the connector 10 and the article 12 are positioned opposite ports on the support 14.

  • the first surfaces 30A and 30B of the members 28A and 28B engage entering end inner surfaces of ports (not shown) on the support 14.
  • the first surfaces 30A and 30B slide along adjacent portions of the entering ends of the ports in the support 14.
  • the inclined nature of the first surfaces 30A and 30B facilitates force application to the legs 18A and 18B and guides the legs 18A and 18B into the ports in the support 14.

Reduction of slot 34A and 34B dimensions produces a reduced profile of the ends 36A and 36B of the legs 18A and 18B. The reduced profile of the ends 36A and 36B allows the ends 36A and 36B to pass through the ports in the support 14.
  • a connector 10 movement facilitating projection is positioned adjacent at least one of the structures 22A and 22B.
  • the projection applies an appropriately directed force to the at least one of the structures 22A and 22B such that the ends 36A and 36B move within the ports in the support 14 from the exiting ends toward the entering ends thereof.
