(ZA9711448-A)      The clamp (10) includes two sprung and movable jaws (14) which define a passage (27) for the battery terminal post (72).The jaws are closed towards one another by a screw operated clamping arrangement (22,40,50).    The screwed part (40), which is prevented from turning, carries a threaded portion (50) having an internal frusto-conical cam surface (60) which closes together the corresponding frusto-conical cam surfaces (28) on the jaws which then clamp the terminal post.    USE -   Rotation of exposed hexagon headed part in one direction causes jaws to close on battery terminal post. Even if cam surfaces bind, rotation in opposite direction frees cam surfaces and allows jaws to release from terminal post.
