A U-strap mounts a nut between the legs of the strap for rotation perpendicular to the longitudinal axis of the strap. The nut is provided with a threaded bore which threadably receives an adjustment sleeve. The adjustment sleeve is also threaded internally reversely to its external threads and threadably receives a stud connected to or constituting a first member to be placed under tension with respect to a second member coupled to or constituting the strap. The turnbuckle is particularly useful in mounting standard wire or rod rigging on a sailboat or sailing yacht.

1. A lightweight, low profile turnbuckle for applying tension between a shroud or stay and chain plate or the like of a sailing yacht joined by said turnbuckle, said turnbuckle comprising: a U-shaped metal strap comprising a circular center section, integral paired arms extending outwardly of said center section generally parallel to each other, permitting said circular center section to rotatably bear a pin and forming a first articulated connection between one of said chain plate and said shroud or stay, a load bearing articulating nut mounted between said strap arms remote from said strap center portion for rotation about an axis perpendicular to the longitudinal axis of said strap, a cylindrical adjustment sleeve bearing opposite threads on interior and exterior surfaces thereof, said nut including a threaded bore threadably receiving said adjustment sleeve, a stud operatively connected to one of said shroud or stay and said chain plate and terminating in a threaded end having threads compatible with the internal threads of said sleeve and being threaded internally of the sleeve such that rotation of said adjustment sleeve causes said sleeve and said threaded end of said stud to move axially through said nut in the direction of said center portion of said strap to apply tension between said chain plate and said shroud or stay as said adjustment sleeve rotates on said threaded end of said stud and internally of said nut. 2. The lightweight, low profile turnbuckle as claimed in claim 1, wherein said strap includes an elongated longitudinal slot through the center portion thereof and extending into said arms for receiving an end of said chain plate, said chain plate end includes a circlar hole therein, and a pin carried by said circular center portion of said strap projects through said hole within said chain plate to form an articulated connection at that end of said strap with said chain plate. 3. The lightweight, low profile turnbuckle as claimed in claim 1, wherein said strap body at its center portion includes an elongated slot extending partially within said arm remote from said load bearing articulating nut, a U-shaped eye-jaw toggle including a circular base portion of a width smaller than the width of said slot has its base portion inserted in said slot, a cylindrical metal pin is borne by said eye-jaw toggle circular base portion and said central portion of said strap to form an articulated connection between said toggle and said strap body, and wherein said toggle includes integral arms extending parallel to each other and away from said base portion, aligned paired holes being provided within said toggle arms and wherein said chain plate includes a circular hole therein and said chain plate projects between said toggle arms, has the circular hole therein aligned with the paired holes of said toggle arms and a pin projects through the paired holes of said toggle arms and the circular hole within the chain plate for effecting an articulated connection between said toggle arms and said chain plate. 4. The lightweight, low profile turnbuckle as claimed in claim 3, wherein said adjustment sleeve includes a radially enlarged head on the end thereof proximate to said stud, and wherein said radially enlarged head is of square plan configuration for permitting coupling to a wrench for effecting rotation of the sleeve and adjustment of the tension provided by said turnbuckle between the shroud or stay and the chain plate connected thereby. 5. The lightweight, low profile turnbuckle as claimed in claim 1, wherein said adjustment sleeve includes at least one pair of diametrically opposite slots extending longitudinally therein, and said stud threaded end includes a transverse hole therein for permitting penetration of a cotter pin, locking ring or the like therethrough to effect an interference between the adjustment sleeve and said strap to lock the turnbuckle after adjustment of the turnbuckle to effect a desired tension to said shroud or stay. 6. The lightweight, low profile turnbuckle as claimed in claim 2, wherein said adjustment sleeve includes at least one pair of diametrically opposite slots extending longitudinally therein for permitting penetration of a cotter pin, locking ring or the like therethrough to effect an interference between the adjustment sleeve and said strap to lock the turnbuckle after adjustment of the turnbuckle to effect a desired tension to said shroud or stay. 7. The lightweight, low profile turnbuckle as claimed in claim 3, wherein said adjustment sleeve includes at least one pair of diametrically opposite slots extending longitudinally therein for permitting penetration of a cotter pin, locking ring or the like therethrough to effect an interference between the adjustment sleeve and said strap to lock the turnbuckle after adjustment of the turnbuckle to effect a desired tension to said shroud or stay. 8. The lightweight, low profile turnbuckle as claimed in claim 4, wherein said adjustment sleeve includes at least one pair of diametrically opposite slots extending longitudinally therein for permitting penetration of a cotter pin, locking ring or the like therethrough to effect an interference between the adjustment sleeve and said strap to lock the turnbuckle after adjustment of the turnbuckle to effect a desired tension to said shroud or stay.
