A dogging device for securing a panic exit and actuation device in an unlatched condition. The dogging device uses a U-shaped spring clip to secure a base plate, a dogging adapter and a dogging hook together. The base plate, dogging adapter and dogging hook are rotated about a common axis by an operator, which can either be a hex shaft or a cylinder adapter operated by a keyed lock, from a disengaged position to an engaged position where the dogging hook engages a control rod of the exit device thereby holding, or dogging, the exit device in an unlatched condition. An over center spring is used to bias the dogging hook into either the engaged or the disengaged position.
