A plug-in connector, especially for hose connections and for use in motor vehicles, including a receptacle and a plug. The receptacle may be provided with an insertion opening for receiving the plug and a groove for retaining at least one locking spring which may be used to lock the receptacle and plug together. The locking spring may include at least one locking section and one unlocking section which can be actuated from the outside of the receptacle. The receptacle may also include an unlocking opening accessible from outside of the receptacle and which discharges into the groove so that the unlocking section of the unlocking spring may extends from the groove into the unlocking opening. The locking spring is retained in the groove in a manner that the locking section is moved outward in a substantially radial direction into the groove when a force is applied to the unlocking section, thus disengaging the locking section from the plug and allowing separation of the plug and the receptacle. The improved plug-in connector avoids the possibility of unintentional unlocking of the receptacle and plug present in the prior art plug-in connectors. In addition, in a plug-in connector in accordance with the present invention prevents the loss of the locking spring.
