The invention relates to piston-type locks preferably for use with vehicles. In the lock according to the invention the stator comprises an aperture opening at its periphery and into the said longitudinal bore, the said aperture receiving an insert comprising radial passages in each of which there are lodged a pair of pistons and a return spring, the said insert being in two parts sliding telescopically one in relation to the other to reduce the effective length of the said radial passages, the said insert comprising retractable stops for the inner radial extremity of each of the said pairs of pistons, the retraction of the said stops causing the liberation of the said pairs of pistons and the introduction of the inner pistons into the radial bores of the rotor.
