An electrical shocking device includes a manipulatable, preferably tubular, housing, one end of which is open and provided with a flange. A plastic tube is movably positioned within the housing against the flange. The plastic tube contains an electric circuit, including a spark gap and circuit members for converting a low direct voltage into a very high voltage, storing a high voltage charge and intermittently discharging the storage device. A pair of probes extend outwardly from the tube beyond the flange, those ends of the probes within the tube being connected to opposite ends of a charge-storing capacitor through a spark gap in series with one of the probes. Batteries and a switch are provided within the housing for supplying the low direct voltage to the circuit upon movement of the tube in response to force on the probes.
