ABSTRACT OF THE DISCLOSURE The present invention provides components for a key- less disposable padlock including a body portion having two sub- stantially parallel bores, a shackle having two limbs occupying the bores when the shackle is locked in the body portion, means within the body portion automatically effecting an interlock between the body portion and the shackle when the latter is sufficiently inserted into the body portion with its limbs occupying the limb-receiving bores, and including a biassing device within the body portion causing movement in a cross bore of a movable substantially rigid engagement member, on occupation of said limb receiving bores by said limbs, from a location in said cross bore which said engagement member is out of engagement with said limbs to a different location in which said engagement member is engaged with one of said limbs and becomes trapped between a limb of the shackle and substantially rigid stop means of the body portion, said stop means stopping movement of the engagement member out of engagement with the shackle, and so that the shackle has its limbs locked unretractably within the bores whereby the padlock cannot be opened without damaging one or more component parts of the padlock.
