Abstract: Apparatus for attaching the end of a length of string or cord to a hollow ball which includes a tubular member having two flanges intended to be positioned one inside the ball and the other outside or towards the outside of the ball, a washer intended to be trapped between the internal wall of the ball and the internal flange of the tubular member, the internal flange and the washer aperture having co-operating part-conical surfaces, and a collar having a conical surface adapted to engage a complementary conical surface on the side of the internal flange of the tubular member remote from the washer, the arrangement being such that, in use, tension or shock loading applied to the string or cord will cause the washer to flex.
