Abstract
The invention provides a keyboard security device for preventing access to a keyboard, such as the digit keys of the keyboard of a digital telephone. The device comprises a base framework with a releasable and removable cover. An engagement member engages a recess in a side member of the framework. Locking means provided by resilient members on the cover engage openings in an inner wall of the framework. A key with spuds corresponding to the resilient members is pivotal in a key accommodating slot to engage the resilient members and disengage them from the openings.
