may be substantially of any typical construction well known to those skilled in the art in general the first wrist encircling means 13 includes a first arm means 19 having a first end 19 39 and a second end 19 34 includes a second arm means 21 having a first end 21 39 and a second end 21 34 and includes a pivot means 23 for pivotally connecting the first ends 19 39 21 39 of the first and second arm means 19 21 to one another for allowing the first and second arm means 19 21 to pivot between an open position in which the second ends 19 34 21 34 of the first and second arm means 19 21 are spaced apart from one another see broken line representation in fig1 and a closed position in which the second ends 19 34 21 34 of the first and second arm means 19 21 meet see the solid line representation in fig1 whereby one of the prisoner 39 s wrists can be encircled by the first and second arm means 19 21 the relationship of the arm means 19 21 and the pivot means 23 allows the arm means 21 to pivot 360 u00b0 about the pivot means 23 as will be apparent to those skilled in the art the first wrists encircling means 13 preferably includes a first lock means for selectively preventing the first and second arm means 19 21 from being pivoted from the closed position to the opened position after being locked into a prisoner 39 s wrists the first lock means may be of any typical construction well known to those skilled in the art for example the first lock means may include a plurality.
