A plate-like housing is adapted to be secured to a wallet, or other pocket-sized valuable, and has formed therein a channel which is substantially transverse to the direction of the article or valuable withdrawal from a clothing pocket, or the like. A pair of slides are reciprocably movable in the channel and are spring-urged outwardly from the article in a transverse direction so that the slide ends are engageable with opposite sides of the pocket confines when the slides are in their extended or outermost positions. The respective ends of the slides each carry a pivotally mounted wing which cammingly engage the opposite sides of the pocket confines, thus increasing the slide dimension in the transverse direction, upon attempted withdrawal of the article from the pocket. The slides are releasably retainable in an inner position, substantially within the confines of the channel, when predetermined segments of the respective ends of the slide are manually compressed, but are not so retained when the manual force is applied to any of the remaining segments of the respective ends of the slide so that the slides are retained only upon manual force being applied to the particular predetermined segment, known only to the wearer, effectively foiling any pick-pocket attempt.
