Abstract: An attachment assembly for securing a toilet seat and cover assembly to its associated commode. The attachment assembly has two pincers which penetrate holes formed in the commode, which holes accept fasteners for accomplishing the above securement. A lever folds downwardly to cause the pincers to clamp the commode, thus securing the seat assembly to the commode. When raised, the lever relaxes the grip of the pincers on the commode, and the seat assembly can be fully removed from the commode without further disassembly. The novel attachment assembly engages pins conventionally furnished to enable the seat and its cover to pivot. When removed, the attachment assembly remains assembled to the seat and cover assembly, and the commode is unencumbered by fasteners, anchors, or the like.
