A device is provided for locking together adjacent pairs of insulated panels for forming walls of walk-in refrigerators, freezers, and the like. Each panel comprises a pair of spaced-apart, parallel, metal wall members. At each end of the panel each panel wall member has a channel along each margin. A latch or strike assembly is disposed between the wall members at each end of the panel and is adapted to engage a mating strike or latch assembly, respectively, of an adjacent panel. A first pair of tubular fastening members are secured to each latch or strike assembly and engaged with the channel of one of the panel wall members. A first pair of planar fastening members are engaged with the channel of the other wall member and are slidably received in the first pair of tubular fastening members. A projection on each of the tubular fastening members engages a receiving aperture on each of the planar fastening members thereby positioning the fastening members and restraining the panel wall members from relative movement towards or away from each other.
