A molded plastic insert is intended for use in a concrete form for making a socket in a concrete structure adapted for engagement with a tool. The insert has an interior bore with an open end, a closed end and two opposed channels extending longitudinally from the open end toward the closed end to receive flanges of a tool. Each longitudinal channel terminates near the closed end in a generally annular channel adapted to receive one of the tool flanges such that the tool can be prevented from extraction from the insert by a quarter turn rotation of the tool flanges in the annular channels in the manner of a bayonet lock. The insert has on an exterior surface one or more generally annular ribs and opposite longitudinal projections corresponding to the interior longitudinal channels. The insert is constructed from two essentially identical molded half pieces.
