A pair of swimming goggles has two ocular assemblies connected by a bridging element, and the means to adjust their separation. The bridging element is composed, symmetrically in relation to a median plane, of a central body and, laterally on either side of the latter, of a lower stalk and an upper stalk which are flexible and attached to an ocular assembly. Each of the two ocular assemblies has first temporary locking resources, at least on a first face. At least one of the stalks is fitted with second temporary locking resources, designed to fit onto the first temporary locking resources so that the temporary locking of the said stalk on the said first face of the ocular assembly is achieved at a distance from the central body chosen by the user.
