Abstract
The present invention relates to a device for filling up a recess left in a concrete wall after removal of a separator terminal, the device comprising a main body including a circumferential step formed around its outer periphery at a longitudinal intermediate location so that the circumferential step defines a diameter-reduced portion and a diameter-enlarged portion of the main body, a threaded hole centrally formed and axially extending in an end surface of the diameter-reduced portion to be engaged with a threaded end of the separator, tool receiving apertures formed in an end surface of the diameter-enlarged portion and in elastic water-swollen rubber cylinder put around the diameter-reduced portion so that an outer periphery of said cylinder is tapered towards the end surface of the diameter-reduced portion and an end surface of the cylinder looking towards the end surface of the diameter-enlarged portion bears against the step of the main body while the end surface of the cylinder looking towards the end surface of the diameter-reduced portion extends at least to the end surface of the diameter-reduced portion.
