The invention of the present application is a guard for limiting the opening of a door (10) with respect to the frame (12) in which it is mounted. The device includes first and second wire forms (14, 42), each having a looped extension portion (38, 46) formed in ends thereof. The looped extensions (38, 46) have apertures (40, 50) defined thereby, which apertures (40, 50) are significantly larger than dimensions of portions (36) of forms (14, 42) received within the apertures (40, 50). A compression spring (52) is disposed intermediate the looped extensions (38, 46) with coils (54, 54', 56) of the spring (52) encircling portions of the forms (14, 42) intermediate the extensions (38, 46).
