A lockout device configured to be lockingly secured to an external structure includes a housing defining an opening sized to receive the external structure, at least one gripping member disposed within the housing and positioned to receive the external structure, and a driving member assembled with the housing. The at least one gripping member is movable in an axial direction between a first position in which internal surfaces of the housing urge the at least one gripping member into gripping engagement with the external structure, and a second position in which the internal surfaces of the housing allow the at least one gripping member to expand to release the external structure. The driving member is operatively connected with the at least one gripping member for movement of the at least one gripping member between the first and second positions. |
