base means;

a pair of horizontal, parallel spindles journalled for rotation in the base means, the spindles being coupled for counter-rotation and spaced apart a distance equal to the distance between the pair of openings in the keeper, the spindles further having outer end portions comprising key means including tabs adapted to engage the fastener gripping elements and displace the gripping elements to the shank-releasing position upon rotation of the spindles;

an actuator supported by the base means and coupled to rotate the spindles, the actuator being pivotally mounted on the base means for movement between a first position in which the tabs are oriented in a non-engaging position relative to the fastener and second position in which the tabs are oriented in a fastener-engaging position, the base means further including a stop for engagement by the actuator in the first position thereof;
