A portable security device for preventing normal opening of a door includes a hard steel strap having a hooked end for engaging a doorjamb and an extension that includes a plurality of aligned rectangular apertures. A U-shaped clip is slidable along the strap extension and has a tang formed in one leg for engagement with any of the apertures. A spring-loaded plunger is captivated between the legs of the U-shaped clip with the plunger extending beyond the clip to engage a door and force the tang into one of the apertures during installation. A bow in the leg in which the tang is formed permits a small lock to preclude movement of the tang out of the aperture and makes the device useful for securing a drawer in a mating frame.
