ABSTRACT:
A grappling device comprises an arm formed from a closed ended, inflatable tube (5) having a plurality of generally parallel, longitudinally spaced bands (15) disposed therearound for limiting the radial distention of the arm when inflated. A longitudinally inelastic, laterally flexible band (20) disposed on a surface of the arm causes the arm, when inflated, to wrap around an object to be gripped. The extent of the inflation of the arm determines the gripping force and geometry of the device.
