ABSTRACT:
A known grid suspended ceiling has a removable panel. A clip will be captive on a ceiling member at the margin of the opening and will also hold an end of a panel ceiling member securely in position with proper location without requiring a tool for removing the panel. The clip has two securing portions which snap into openings in the margin ceiling member. The clip has jaws connected at their lower ends to wings which can be moved to open the jaws. The jaws have detent portions with horizontal upper surfaces. The panel is merely pushed up into the opening, the detent portion being cammed back and then snapping home into position. To remove the panel, the appropriate wing is pushed, withdrawing the detent portion and allowing the panel to drop down.
