Abstract
An assembly system for providing sealed assembly between a miniature pump whose body is supported by a sleeve, and a reservoir of small capacity, by forced internal or external engagement, wherein the side wall of the sleeve or of the reservoir includes a grooved zone forming a vent which is longitudinally terminated by an adjacent smooth zone; the zones being designed to slide with radial clamping over the entire length relative to a smooth portion of the facing wall of the reservoir or of the sleeve for the purpose of progressively closing the grooved zone and coming into sealing contact with the smooth zone at the completion of the engagement.
