Ground anchors. - The anchorage a for the height-adjusting means h of a tennis net claimed in the parent Specification is modified to prevent accidental detachment of the height-adjusting means by providing the upper surface of the upper piston b, or of the block, with a pivoted hook member e, a fixed vertical projection f and a spring plunger g. To insert the eye h<1> of the height-adjusting means the hook member e is rocked backwardly against the pressure of the spring plunger to provide a gap between the hook member and the projection f.
