A tamper-evident closure for a container, the closure including a first portion including inner and outer parts, and a second portion, wherein the outer part is movable relative to the inner part from a first position in which the outer part is immediately adjacent the second portion to a second position in which there is an unobstructed gap therebetween, and wherein the inner and outer parts are adapted to become irreversibly locked in the second position so that the outer part cannot be moved back to the first position to close the gap, wherein means are provided to prevent the inner part from moving relative to the second portion until the outer part has reached the second position.
