Each of the flanges 3| is provided with Fig. 3 is a sectional, perspective elevation a plurality of apertures 33, and guide flanges showing a portion of the acoustical ceiling con- 34 extend outwardly from two opposite edges of struction on a large scale, each aperture. A resilient clip 35 has one leg Fig. 4 is a sectional elevation through the ceilsecured to flange 3| by a spot-weld 3B, or other ing construction taken adjacent a vertical buildsuitable fastening device. The clip 35 is proi W ll. vided with a resilient loop 31 which terminates 6 in a spring flange 38 having an inwardly extending latching lug I9. The lug 39 is provided with a flanged cam surface 40 and a lower locking shoulder 4 I As the metal membrane 24 is moved upwardly during the erection of the ceiling, the cam surface 40 engages the lower outer edge of the runner flange 20 and is deflected inwardly until it rises above said flange, and then the lug ll snaps inwardly with the latching shoulder 4i seated snugly on top of the runner flange 20, thus securely attaching the membrane 24 to said runner ll. Adjacent the edge of a ceiling where the ceiling surface it meets a vertical wall 43, an Lshaped runner 44 is secured to the wall 43, as by nails 45. The runner 44 has an outstanding horizontal leg 46 which engages a clip on the flange 3! similar to clip 35. The runner 44 also has an ofl'set upper flange 41 which engages with a .downwardly extending lug 48 formed on the end of each of the cross bars 2|.
It will be noted that with the form of attaching clip shown in Figs. 1 to 4, the axis of the loop extends substantially vertically, and all points of the attaching clip are down below the upper edge of the flange 3|, so that the vertical space necessary for the acoustical structure is reduced to a minimum. However, if desired, the attaching clip may be turned vertically as shown in Figs. 7 and 10, in which case the axis of the clip 50 extends substantially horizontally, said clip being secured to a membrane flange 5| which is somewhat wider than the flange II. The clip III is provided with a resilient loop 52 which terminates in an outwardly inclined cam flange 53 which extends through an aperture 54 formed in the flange II. An inwardly extending latching flange 55 is formed on the lower end of the cam flange BI and serves to seat on top of one of the runner flanges 24.

We would state in conclusion that while the illmtrated examples constitute practical embodiments of our invention, we do not wish to limit ourselves precisely to these details, since manifestly, the same can be considerably varied without departing from the spirit of the invention as deflned in the appended claims.
