Abstract: A valve assembly suitable for both high and low pressures, includes a base plate (1) a first connection surface (3) and a valve housing (2) which forms a corresponding facing second connection surface (4), a pressure-tight connection which is useful for a battery arrangement and does not consume space elsewhere required. The connection can be created and maintained by a yoke (9) which grips below the valve base plate (1) in a longitudinal direction (8), having arms (9a, 9b) which extend on narrow side surfaces (1a) of the base plate (1) and of coupled valve housing (2), on which arms detent projections (10), which engage into corresponding recesses (2a) of the valve housing (2), are provided. Ease of assembly and disassembly is provided by additional projections (11) which engage in detent troughs (12) on the base-plate side surfaces (1a).
