To monitor a patient, a combined allegator clip and switch is fastened to the patient by a cord having a length of between five inches and five feet. The other end of the cord is connected to a switch which is activated when the patient moves beyond the length of the cord to cause a message to be announced. If the allegator clip is removed, another circuit activates the alarm to play the voice message and provide an alarm to a caretaker at a remote station. The fastener is an alligator clip having first and second jaws and a spring for biasing said first and second jaws together, whereby said alligator clip may be fastened to clothing. When the jaws are separated by clothing, two conductors are separated but when the jaws contact each other, the conductors are closed to activate the voice message.
