Abstract
A door lock and alarm in the form of a case which is attached to the exterior door handle by a clamping mechanism that stops movement of the case with respect to the door in all degrees of freedom, but allows the handle to turn inside the case. The case is provided with a lockable cover so as to permit an authorized user to open the cover and operate the door handle. An alarm device can be provided within the case to indicate tampering with the door lock.
