A new article of flexible and springy though rigid enough water impervious material provided with spikes or bristles or open web of crinkled filaments or rough indented openings to be installed around any conventional stopper for preventing hair, hairpins, or any other object carried away with the water flow during the taking of showers or washings or the like, from entering and clogging the drainpipes of bathtubs, lavatories and the like, through an entangling action carried out by said spikes or bristles or web or rough indented openings, and said article having a body which is shaped to be adapted to surround the lifted conventional pop-up stoppers or the like, of the drain control systems of bathtubs, lavatories and the like, and which may take any of several preferred cross section forms, such as for example, a hollow core elongated semicylindrical form which is integral with a flat imperforate lower portion or base, providing several preferred undersurfaces or a hollow core cylindrical form, or a vertical strip-like form, or a cup-like form, or a stepped strip-like form, and said forms being constituted by a net-like structure with a plurality of openings, which in the three last mentioned cross section forms, is integral with imperforate zones and with an outwardly directed surrounding flexible flat base having a central hole defined therein and the base providing several preferred undersurfaces.
