Abstract
A safety spring lock for locking an air pattern control in a diffuser includes a normally bowed strip carrying a retainer clip. The strip is flattened to engage the clip with a fixed part of the diffuser, the clip engages the diffuser and that engagement and the inherent bias of strip hold the spring lock in place in the diffuser. The safety lock includes a U-shaped portion spaced from the retainer clip and connected to the retainer carrying portion by a normally bowed strip which is flexed to a flattened position to locate the U-shaped portion adjacent to portion of the movable air pattern conrol when it part of the diffuser. The U-shaped portion is urged into engagement with a portion of the air pattern control to prevent movement thereof in the diffuser which would otherwise be sufficient to remove the air pattern control from the diffuser.
