A removable retaining device is provided for a container lid (1, 1a), having a continuous strengthening recess (2) therearound in its outer surface (3) adjacent its rim (4), and being a press fit in a corresponding aperture in a container (5) such as a paint can, which device is a continuous ring-like member (10) made of springy substantially rigid material having a substantially U-shaped cross-section, of which the innermost limb (11) is continuous or substantially continuous and the outermost limb (12) is interrupted at intervals to provide a plurality of spaced apart fingers (13) extending from the base (14) of the member (10) spaced from and substantially parallel to the innermost limb (11), with each finger (13) having a tooth-like projection (15) extending therefrom, at or adjacent its outermost end (16), towards the innermost limb (11), so that with the lid (1, 1a) fitted in the container aperture the member (10) can be fitted thereover with the innermost limb (11 ) projecting into and at least substantially filling the lid strengthening recess (2) to strengthen the container (5), with the base (14) fitting over the lid rim (4) and container rim (7) to provide further cushioning and protection for the lid and container rims (4,7) against a blow on the container rim (7), and with the outermost limb fingers (13) fitting around the container exterior with the tooth-like projections (15) releasably clipping under the container rim (7) removably to retain the member (10) on the interfitting lid and container end to provide a retaining action on the lid (1, 1a) against internal pressure on the lid (1, 1a) due, for example, to a blow on the container base, tending to force the lid (1, 1a) out of the container aperture and off the container (5).
