A fastening assembly for crash helmets is disclosed. The assembly is characterized in that the locking elements comprise a locking pin which is spring biased and slidable between two shoulders in a male member. The locking pin is approximately an I-shaped cross section with the I having two flanges and a web. The male member comprises a rigid tongue-shaped section having in its end a recess through which the closed position of the fastening of the web of the locking pin projects, and the inner limiting faces of the flanges are chamfered such that the tongue, when being inserted, acts on an oblique face pushing the pin away against the biasing action of the spring. |
