The keyless lockable security device is in the form of a padlock or clevis pin. It consists of a body member(1) having at least one blind bore(2) & a male member(9) having limbs(10) corresponding to the munber of blind bores, insertable in the bore, & latching in them. Each of the bores(2) and the limbs(10) have an annular recessed portion(3 & 12) of substantially crochet hook form accommodating a split annular latching ring(17) of spring steel. The free end surface of the limbs may be provided with aligned slots into which is inserted a pin through a bore(21) transverse to the blind bores to prevent rotation of the limbs if the limbs are separated from one another.
