Claim 10:
11. A restraining device comprising:
a housing defining an interior space, the housing having a pair of apertures positioned therein, the apertures being positioned singly in a front end and a rear end of the housing, the housing having a top, a bottom, and opposed sides, the opposed sides tapering from proximate to the rear end to the front end such that the front end is circumferentially smaller than the rear end;
a strap having a first end engaged to the housing, the strap extending from the housing loopedly back through the pair of apertures defining a loop, such that a second end of the strap is external to the housing, wherein the loop is configured for inserting hands of a person such that the strap is positioned around wrists of the person, the strap having a plurality of holes positioned therethrough and extending from proximate to the first end and the second end, each hole being ovally shaped, the strap comprising plastic;
a handle engaged to the strap proximate to the second end, wherein the handle is configured for grasping in a hand of a user, positioning the user for pulling on the handle for tightening the strap around the wrists of the person, the handle being cylindrically shaped;
a pair of plates, each plate being engaged to a respective opposed end of the handle, wherein the plates are configured for deterring slippage of the hand of the user off of the handle;
a grip engaged to the handle, wherein the grip is configured for enhancing a grasp of the hand of the user upon the handle, the grip comprising rubber, silicone, or elastomer;
a locking unit engaged to the housing, positioned in the interior space, and being configured for selectively engaging the strap for preventing expansion of the loop, the locking unit comprising an arm hingedly engaged to the housing, such that a first terminus of the arm is external to the housing and such that a second terminus of the arm is positioned in the interior space and for selectively inserting into a respective hole of the plurality of holes, the arm having a spring engaged thereto such that the arm hinges as the strap slides through the housing by action of the user pulling the handle, concurrent with tensioning of the spring, such that the spring is positioned for rebounding for inserting the second terminus of the arm into a respective hole for preventing expansion of the loop, wherein the first terminus of the arm is configured for depressing by a digit of the hand of the user for extracting the second terminus from the respective hole, positioning the loop for expansion for releasing the wrists of the person; and
a connector engaged to the handle, the connector comprising an eyebolt.
