A plastic plug for anchoring objects in support structures comprises an expansible portion and an elongated neck having a head portion with a flange for supporting an object being secured to the support structure. The elongated neck is formed of two spaced expansible legs and has an elliptical crosssection which merges into circles at two end portions thereof. The expansible portions of the legs are provided with longitudinal grooves which form a widening of the longitudinal bore in the head portion. |
