A locking device serves to lock an electronic module to a bank of terminal blocks, characterized by a body member having at least one pair of integral parallel spaced legs that extend downwardly within a corresponding T-shaped vertical groove contained in one end of a first one of the terminal blocks. The legs are resiliently biased apart and are provided at their free ends with hook or catch portions that extend laterally outwardly from opposite sides of the legs into corresponding locking recesses contained in opposite side walls of the groove, respectively, thereby to lock the body member with the bank of terminal blocks. The adjacent end of the body member contains a longitudinal chamber that slidably receives a locking member that is displaceable between retracted unlocked and extended locking positions relative to the body member. Accordingly, when the locking member is in the retracted position and a vertical locking tongue of T-shaped cross-sectional configuration integral with a side wall of the housing of the electronic module is inserted within the T-shaped groove of a second terminal block of the bank, the locking member may be displaced to its extended position above the locking tongue, thereby to fasten the module with the terminal block bank.

[ What is claimed is:] [1.] Fastening means (10) for locking the housing (8) of an electronic module (5) to a bank (1) of at least two stacked terminal blocks (2) each containing a T-shaped groove (7) for slidably receiving a corresponding T-shaped tongue (9) mounted on an adjacent wall of the housing, comprising:(a) a body member (11) of generally rectangular cross-sectional configuration having top, bottom, side and end portions, said body member including:(1) at least one pair of integral generally parallel spaced legs (12) that extend downwardly from said body member bottom portion, said legs being resiliently biased apart and having free end portions provided with catch hooks (13) that extend outwardly in opposite directions from the remote sides of said legs, respectively;(2) one end portion of said body member containing a longitudinally extending guide chamber (15); and(b) a locking member (16) slidably mounted in said guide chamber for displacement in a direction generally normal to said catch legs between retracted unlocked and extended locked positions relative to said body member;(c) said body member being operable to a mounted position on a first terminal block with said catch legs extending within the associated T-shaped slot of the first terminal block and with said catch hooks engaged in corresponding recesses (14) contained in the opposed side wall surfaces of the slot, whereby when said locking member is in its retracted position and the module housing is displaced relative to the terminal block to introduce the housing tongue within the T-shaped slot of a second one of said terminal blocks, said locking member may be displaced relative to said body member toward a locking position opposite the groove containing the tongue, thereby to lock the tongue within the groove, and the housing with the terminal block bank.
