Lock devices for installation on a serial bus male connector plug that prevent access to, and connection of the plug to other devices, such as memory storage devices, have a housing with a receptacle which is installed onto the serial bus male connector plug to cover at least a portion of the male connector plug, and contain a locking mechanism and retaining member moveable between an unlocked position allowing disengagement and removal of the plug from the receptacle, and a locked position with plug securely engaged in the receptacle to prevent connection of the connector plug to a female serial bus connector of another device and unauthorized access to data stored in the memory of memory storage devices. The lock device may have a shackle and a cap-holding tether attachment and may be utilized with conventional security cables and locking devices to also prevent theft of the memory storage device.
