The spacer is adapted for a rolling bearing comprising an inner ring, an outer ring and at least two rows of contact rollers disposed between raceways provided on the rings. The spacer comprises opposite inner and outer portions facing one another, a first lateral portion extending transversally between the inner and outer portions and connected to the portions, and a second lateral portion facing the first lateral portion and extending from the outer portion towards the inner portion. The inner and outer portions delimit together with the lateral portions a pocket configured to receive at least two superposed contact rollers. A free edge of the second lateral portion defines with the inner portion an aperture in order to open laterally the pocket on the side opposite to the first lateral portion.
