An improved spigot actuating device is provided for actuating the spigot on a spout of bag-in-box potable liquids. The device comprises a collar for mounting onto a spout of a large standard diameter. A spacer is provided in the shape of an arcuate cuff, that makes all smaller spouts emulate the large standard diameter. The collar is flexible and resilient, arcuate, terminates in legs, and extends around the spout more than half way. The collar mounts graspingly the spout along a grasp arc that is larger than 180 DEG , which makes for a secure attachment. Teeth are provided on the collar to render the attachment more secure. A pair of pinchers can be squeezed together to increase the separation between the legs, to permit mounting and removing the collar. The device further includes an actuator that is pivotable with respect to the collar around a rotation axis. The actuator has a handle for the user, and a cam with a specially designed upper surface. As the handle is rotated from a standby position, the upper surface engages the lever and pushes it open. In addition, design is such that the handle can be released at a full open position, where the egress path for the liquid is the widest possible.
