Abstract
Una grapa perfeccionada para tubos, caracterizada esencialmente por estar constituida por un cajetín que en su interior lleva en sentido longitudinal un husillo para actuar como tornillo sin fin sobre un fleje que presenta la particularidad de llevar en toda su longitud una pluralidad de ventanas distanciadas en equidistancia adecuada al paso de los filetes del husillo, para constituir en su arrollamiento bajo el cajetín la corona dentada correspondiente a dicho husillo, el que ejercerá tracción del fleje para su ajuste al tubo.
