The invention relates to a reinforcement (2) for a glove (17), in particular a goalkeeper glove comprising a) an arrangement (3) of several interconnected first elements (3a, , 3f), b) several second elements (4a, , 4e) connected or connectable to the arrangement of the first elements (3a, , 3f) in such a way that at least two stopping surfaces (14, 15) are formed between at least two second elements (4a, , 4e), in particular between all second elements (4a, , 4e), wherein c) the arrangement (3) of the first elements (3a, , 3f) can be bent from a substentially stretched state to a curved state during a forward movement and unbent from the curved state to the stretched state during a back movement, wherein d) in the curved state, d1) an interspace (11, 32) is formed between the adjacent first elements (3a, , 3f) and d2) and an interspace (16) is formed between the stopping surfaces (14, 15) of the adjacent second elements (4a, , 4e) in the stretched state and e) said stopping surfaces (14, 15) of the adjacent second elements (4a, , 4e) are at least partially connectable therebetween and counteract to the back movement.
