A patient monitoring system (10) having a battery (14) and an audible message device (16) mounted in a housing (12) and electronically connected to a clip (18) that attaches to a patient's clothing (100). A connector strap (20) attaches the housing (12) to a clamp (22) such that movement of the patient beyond the range of the strap (20) causes the clip (18) to be removed from the clothing (100) and bring electrical contacts (32 and 34) into contact to activate the device (16). The connector strap (20) has a buckle (38) to permit adjustment in the length of the strap to alter the range of movement of the patient.
