Abstract: The device for retaining an article includes a stiff member for engaging simultaneously an object (such as a wallet) to a clothing article, and a flexible member which has a first and a second position with respect to said stiff member. In the first position the flexible member engages the clothing article with a spike so that the object cannot be removed.

Abstract: The device comprises a staple provided with means for attaching it to the article to be retained, for example a billfold. This staple supports a steel wire, which is bent so as to form simultaneously a spike crossing the staple from one wing to the other and a control means provided with a cap. When the staple is placed in a pocket, the spike penetrates into the fabric when an effort is made to withdraw the billfold. The spike can be retracted by applying pressure to the cap, the wire coming to rest on the base of the cut-out of the staple. Locking means formed by a lug and a groove in the cap make it possible to prevent axial movement of the cap.
