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