Abstract
A security device for protection against pickpockets comprising a clamp intended to be releasably clamped on a top edge of a pocket and connected to a card-size casing by a flexible connecting element is disclosed. The card-size casing is adapted to be received in a compartment inside a purse which, in turn, is received in the pocket such that pulling the purse out of the pocket causes a lock bolt on the clamp to tightly secure the clamp to the pocket. A pull rod is movably fastened in the casing and connected to the flexible connecting element to trigger an alarm circuit when the casing is pulled outwards.
