ABSTRACT:
A reusable, releasable, tamper-resistant fastener (10) for releasable attachment to the free end of shaft (14) is provided. The fastener comprises a hollow body (20) having a lower portion (24) and an upper portion (26) defining a cavity (28) therebetween. The lower portion has an aperture (30) therethrough and the upper portion has an elongated slot (32) therein. The central portion (38) of the slot is aligned with the aperture. A one-piece spring steel clip (22) is nonrotationally received in the cavity and has a nondeformed position for retaining a received shaft and a resiliently deformed position for release of a retained shaft. A specially configured tool (T) is provided for insertion through the slot and then rotation relative thereto for selective resilient deformation of the clip to selectively release retained shafts.
