The invention relates to a test part arrangement (23) for the production of an explosion-proof housing (15). The test part arrangement (23) comprises a test part (21) that can be used as a housing part (16) in the production of the housing (15). The test part (21) is completely passed through by a test channel (25) which extends from an outer orifice (27) to an inner orifice (28). A closure part (22) of the test part arrangement (23) can be introduced without a tool and straight along an insertion direction R into the test channel (25) to a closed position S, in which it is locked and secured against a movement out of the test channel (25). The closure part (22) forms with the test channel (25) a flame-proof gap (62). A security device (48) with at least one detent element (49) is provided on the test part (21), wherein said detent element interacts with at least one counterpart detent element (68) on the closure part (22) and holds the same lockingly in the closed position S.
