PCT No. PCT/FR85/00237 Sec. 371 Date May 5, 1986 Sec. 102(e) Date May 5, 1986 PCT Filed Sep. 4, 1985 PCT Pub. No. WO86/01637 PCT Pub. Date Mar. 13, 1986.The invention relates to modular housings for electrical apparatus distributed between the aligned and superposed modules (1) of the housing, which modules are assembled by means of fixed transverse catches (3) and flexible longitudinal lugs (2) which are provided with catch-hooking windows (4). The catches (3) are each provided with an inlet slope facilitating lug sliding when the modules are stacked, they also include snap-fitting chamfers (14) enabling the modules to be reversibly hooked together, together with retaining ramps (7) enabling the modules to be positively locked together. The thrust rims (6) of the windows can pass from the snap-fitting chamfers (14) to the retaining ramps (7) only by applying external pressure to the free ends of the lugs so as to cause the lug material to creep.
