Anti-rotation clip for tightening and loosening nuts and bolts

The combination of an anti-rotation clip and a flanged connection having an associated polygonal nut-like member with a vertically opposed bolt head or nut connected therewith to facilitate tightening or loosening of the nut-like member and eliminate the need to use two wrenches for tightening or loosening the nut or bolt, the combination comprising:

• a generally L-shaped member having a horizontal portion and an integral vertical portion at one end thereof extending generally perpendicular thereto;
• a polygonal opening extending vertically through said horizontal portion having a plurality of discrete angled sides configured to surround and engage the sides of the polygonal nut-like member;
• said vertical portion having an inner surface facing said opening and spaced a predetermined distance therefrom sufficient to be received in generally radially spaced relation closely adjacent to the peripheral surface of a flange of the flanged connection with which the nut-like member is associated;
• and
• a manually operated release tool extending extendibly and retractably through said vertical portion and having an end engageable with said peripheral surface of said flange;
• wherein
• said opening is placed onto the polygonal nut-like member to surround and engage the sides thereof with said vertical portion disposed in generally radially spaced relation closely adjacent to the peripheral surface of said flange so as to engage said peripheral surface and prevent rotation of said nut-like member when torque is applied to the vertically opposed bolt head or nut connected with said surrounded nut-like member;
• and
• said release tool is selectively extended to engage said peripheral surface of said flange to pull said vertical portion outward therefrom to facilitate disengagement therewith in the event that said vertical portion becomes lammed against said peripheral surface.

• and
• a spring biased plunger having a radially extendible and retractable end protruding into said opening to engage a flat surface of said nut-like member when said opening is placed onto said nut-like member;
• wherein
• said opening is placed onto the -polygonal nut-like member to surround and engage the sides thereof with said vertical portion disposed in generally parallel spaced relation closely adjacent to the peripheral surface of said flange so as to engage said peripheral surface and prevent rotation of said nut-like member when torque is applied to the vertically opposed bolt head or nut connected with said nut-like member;
• and
• said plunger releasably retains said nut-like member in said opening after it has been removed from the flanged connection and thereafter allows said nut-like member to be released by pulling or pushing it from said opening.
