A flip-up attachment for securing a windshield or other protective device to a helmet including a first element which is removably secured to the helmet in a sealed relationship therewith and a second element which is pivotally attached to the first element and includes as an integral part thereof means whereby commercially available face shields may be removably secured thereto without modification of either the attachment or the face shield. The two elements of the flip-up attachment are so arranged and configured that when the windshield is in the down or face protecting position a seal is formed between the two elements. The attachment between the two elements of the flip-up device includes a means whereby the relative friction may be adjusted, thus assuring that the windshield will be retained in its upward or in a semi-upward position when so desired. The two elements are latched together when in the downward position thus preventing the inadvertent relative movement during usage.
