"Improved level", comprising a general support body with a smooth wall draft, in which the level device is adapted, formed by a cylindrical core with a threaded sector and a peripheral widening, forming a port for the seat of a ring elastic joint; an annular piece threaded on the commented core by pressing between them the elastic joint deforming it and radially so that it exerts pressure on the walls of the draft of the general body to retain on this the whole device.
