In a connecting arrangement on first and second parts which are to be connected, the first part carries an extension and the second part has an opening into which the extension engages when the parts are in the connected position. The extension has an aperture. A projection extending into the opening in the second part engages in the aperture when the parts are in the connected position. An arresting tongue projects into the aperture in the extension. When the two parts are brought together the arresting tongue is pivoted by the projection into the position in which it bears against a region of the boundary wall defining the opening in the first part and thus secures the parts in the connected position.
