Sister hook type tool assemblies (20, 21) comprise mating arms (26, 28) having C shape lower ends grip portions that terminate in jaws (42). The arms preferably are held between two spaced apart housings (22, 24). The arms, and housings when present, are held together by a fastener (70, 72) at the upper end of the assembly. The arms pivot relative to one another and to the mated housings. Each housing has a pair of forks (54) at one end which define a U shape opening (65). An object received in the opening is retained when the jaw ends arms overlappingly close the fork opening, due to action of spring (40). The V shape lower end contour (70) of the mated arms and inclined surfaces (56) of the fork tips cause a rigid object to open the jaws when the tool is thrusted at the object. The jaws then close under spring force, capturing the object. Optional locking means (36, 76) are used to keep the jaws from unintentionally opening.
