The invention relates to a base (1) for an electrical protective-earth conductor terminal (2) for connection to a supporting rail (5) which has laterally projecting limbs (3, 4), having two base elements (11, 12) which consist of bent sheet-metal parts and can move relative to one another and between which at least one spring element acts, the base elements (11, 12) having at their outer ends, pointing away from one another, base ends (9, 10) for in each case engaging under a limb (3, 4) of the supporting rail (5), at least one base end (9), which is designed as an intrinsically rigid bolt, being movable in the direction of the associated limb (3) and, against the spring force of the spring element (14), away from the associated limb (3) for connection to the supporting rail (5) and, in the connected position, engaging under the associated limb (3) in a positively locking manner, the two base elements (11, 12) being arranged such that they at least partially overlap and each base element (11, 12) having a bent supporting limb (22, 23) in the region of the overlap and the spring element (14) acting on the supporting limb (22, 23) in such a manner that the base ends (9, 10) are clamped onto one another. In order to provide a base which consists of as few components as possible, can be handled and assembled easily and is at the same time cost-effective, it is provided according to the invention that the spring element (14) be designed as a leaf spring, which is designed integrally with one of the supporting limbs (22, 23). <IMAGE>
