arcuate hook member 22 at opposite ends of the body and an elongated shank portion 24 therebetween and connecting the two the hook 22 is seen more clearly in fig3 to depend from the shank 24 and may be of reduced cross sectional area relative thereto the termination or end of the hook 22 may advantageously taper to a point 26 as shown to facilitate its use in a manner that will be described hereafter an elongated latching member 28 is pivotally connected at one of its ends to the shank 24 adjacent its juncture with the hook 22 as with a screw or rivet 30 the free end of the latching member 30 is thus disposed for movement through a substantially semi circular arc as indicated by the arrows in fig1 such that as the member 30 is urged in the direction of the hook 22 and away from the handle 20 its free end makes contact with the hook point 26 and is prevented form further or continued movement in the same direction as seen in phantom perspective the latching member 30 in this position forms a closure or bridge from the shank 24 to the hook point 26.
