Integral crash-helmet for motorcyclists, sports-competitions and the like, transformable into a "Jet"-like open helmet, includes a frontally open rigid cap (1) and a rigid chin protector (3), removable and fastenable in seats (3a) provided in the two flanges (2-2a) protruding from the cap (1) base by the association of removable embedding and hand-operatable locks, provided correspondingly on the external faces of the flanges and on the internal faces of the chin protector. The removal of the chin protector (3) transforms the integral helmet, which complies with the stress-resistance requirements provided for integral helmets, into an open "Jet"-like helmet, and vice-versa.
