The invention relates to a cap (1, 1′) for closing a bottle (2) or similar container having a projecting outer annular ridge (10) in the region of its container aperture. The cap (1, 1′) has an inner cap section (3) with spring pins (7) which engage the annular ridge (10) of the bottle (2) from under in the closed position and can be secured in this engaged position by an outer cap section (4) in the form of a slide ring. In order to be able to fit or remove such a cap (1, 1′) on or from an infusion or transfusion bottle (2) with little effort and to be able to properly recycle the plastic cap material, the invention proposes that the outer cap section (4) have a plurality of security projections (14) around its periphery between which there is a disengagement aperture (26), the outer cap section (4) and the inner cap section (3) are secured together so as not to rotate, when the cap (1, 1′) is closed, by means of at least one releasable anti-rotation device and after the anti-rotation device has been released both cap sections can be mutually separated by means of turning and then axially pushing the outer cap section in relation to the inner section (cf. FIG. 5).
