Provided for locking the plunger positively and selectively against manipulation to effect opening of the gate is a position-changeable locking element mounted on the plunger for adjustment into and out of effective reactive engagement with the swivel's body. The locking element is captured on the plunger to prevent its inadvertent removal.</p> |
