An anti-rotation clip is adapted to be attached to a fastener or connector assembly to ensure the tightened threaded connection of the assembly. The anti-rotation clip in one embodiment of the invention includes one or more co-axial clips to radially and forcibly grip one or more hexagonal parts rotatable to a body, and a pair of tang members extending from one clip to engage a pair of grooves having flat bottoms on the body to prevent the hexagonal parts from rotation and the clip from axially moving away relative to the body. In another embodiment of the invention, two co-axially connected clips are adapted to radially and forcibly grip two connectors, having hexagonal exteriors, which are in a tightly threaded connection to a body and may be loosened in opposite rotary directions. The two clips lock the two connectors together to prevent the loosening of either one. An axially spaced apart tang member restrains a flange member on the body to prevent the clip from displacement from its axial position. The anti-rotation clip is simple in structure, easy for use and no plastic deformation is required during installation so that stress concentration is avoided which is especially good for aerospace applications. |
