The monitoring device has a contact transmitter (14) and sensor each set in profiled recesses and provided with noses for engaging behind the rear-cut projections of the recesses. At least one of the noses is movable and is set spring-elastic in the transmitter or sensor body. The movable nose can be formed by a screw tip (21). A cable channel is formed in the sensor body.
