Abstract

A screen sleeve for use in combination with a hardenable mass for securing an anchoring element, inserted into the sleeve, in a receiving material where the sleeve is formed of an axially elongated, woven wire mesh, cylindrically shaped tubular member closed at one end and open at the other. The tubular member has a flange at its open end. Adjacent the flange, one or more outwardly projecting protrusions are formed from the wire mesh defining the tubular member.
