The invention relates to a beverage producing machine (1) comprising a housing (3) and a connector (20) for attaching an ingredient container (C) to said housing. The connector comprises a bottom wall (23) with a passage (25) for dispensing said ingredient towards the interior of the housing and a locking seat for said ingredient container. The locking seat comprises a ridge member (29) at least partly surrounding the bottom wall, wherein at least one resilient element (47, 49) is provided in said locking seat and constrained to the ridge member. The ridge member (29) is provided with at least one tangentially extending slot (39, 41) with an edge (39A, 41A) extending substantially parallel to and distanced from the bottom wall. The at least one resilient element projects from the edge of the slot towards the bottom wall (23) and is arranged to reduce backlash between an ingredient container and said connector when said ingredient container is locked to said connector.
