Abstract: A pipe junction holder which comprises a substantially annular body with which are formed a plurality of spaced clamping blocks comprising a vertical front wall, a pair of vertical side walls, and a lateral top wall which extends descendingly or downwardly away from the front wall and is formed with a non-threaded hole which is elliptical in shape and extends with an inclination relative to a longitudinal axis of a pipe on which the pipe junction holder is mounted. Within the hole is received a bolt having a shank with an integral annular flange formed therewith, in such a manner that an upper slanted surface of such an annular flange is slidable along a lower slanted surface of the top wall. In addition, on a threaded end portion of the bolt shank is engageably mounted a pipe pressing member including a pair of edges formed on its bottom end surface.
