A bridge plug positionable within a well casing and adaptable for sealing the casing comprises a flexible sealing element positionable to be driven into a sealing position by the force of a compressing mechanism which includes a first component held stationarily below the sealing element and a second component positioned movably above the sealing element. Coincidentally with the compressive movement of the sealing element, an upper and a lower member of the compressing mechanism provide means for securing the bridge plug in position, fracture, with the fractured portions of each driven securely against the inner wall of the casing. Cooperative portions of the bridge plug have components which interlock in a manner to guide a slip radially outwardly toward the inner wall of the casing for equal distribution against the casing wall upon fracturing. The even distribution of the slip portions provide for equal distribution of the lateral force upon the sealing element upon being compressed.
