The locking element comprises a wheel (20) pivotally mounted on a plate (14) fixed to the forward inside surface of the oven. This wheel comprises a first surface (A) comprising two abutment lugs (22 and 23), a safety lock constituted by a blocking finger (25) fixed on the second surface (B) of the wheel and controlled by a safety spur (24) that projects through an opening (23') transversely to the first surface (A) and adapted, either to come into abutment with stop boss (26) of the plate, or to permit the rotation of the wheel. Application to all closure devices, particularly to a household microwave oven to prevent operation thereof by e.g. a child, when the door is open.
