A coin slide (11) bearing a coin is movable into a casing (2) of a coin lock (1) to release a locking member (14) and allow full insertion of the coin slide (11). In this position a space (recess 20) in the coin slide (11) is aligned with a space (aperture 21) in a coupling member (8) and with a space (aperture 19) in a casing portion separating the coin slide (11) and the coupling member (8). A locking member (e.g. ball 18) in the apertures (19 and 21) may now be moved upwardly, on pulling of the coupling member (8), to occupy the recess (20) and the aperture (19) so as to allow complete withdrawal of the coupling member (8), e.g. to free a shopping trolley. The coin is released by reversing the procedure on re-insertion of the coupling member (8).

Une glissoire (11) pour pièce de monnaie se déplace vers l'enveloppe (2) d'une serrure (1) actionnée par une pièce de monnaie pour libérer un élément de blocage (14) et permettre l'insertion complète de la glissoire (11). Dans cette position, un espace (évidement 20) dans la glissière (11) est aligné avec un espace (ouverture 21) dans un élément de couplage (8) et avec un espace (ouverture 19) dans une portion de l'enveloppe qui sépare la glissière (11) de l'élément de couplage (8). Un élément de blocage (par exemple bille 18) agencé dans les ouvertures (19 et 21) se déplace alors vers le haut lorsque l'on tire l'élément de couplage (8) et va se loger dans l'évidement (20) et dans l'ouverture (19), ce qui permet de retirer entièrement l'élément de couplage (8), pour libérer un caddie, par exemple. On libère la pièce en inversant l'opération après réinsertion de l'élément de couplage (8).
