Disclosed terminal blocks are secured in position in an opening in a sheet-metal panel, with terminal screws extending at a small angle to the panel. Screw-driver thrust against the screws is resisted by engagement of the body of the terminal block against an edge of the opening. Resilient detents for holding the terminal block assembled to the panel are at the sides of the terminal block and are not affected by screw-driver thrust. The terminal block is locked to the panel along one edge of the opening by hooks extending from barriers between the circuit connectors. A circuit coding strip is carried by these hooks, useful in preliminary wiring and after the block is mounted on the panel.
