DE 102 42 429 B4 discloses a plug with a plug housing, a slider, and an elastic element that is supported between the plug housing and the slider and establishes an elastic pretension when the slider is moved. The plug is to start to separate from a plug socket if the resulting elastic pretensioning force is greater than the connecting force of the contact elements. However, the connecting force of the contact elements can decrease over time as a result of wear, which can lead to a separating movement varying over the useful life. If, in addition, a user holds the plug housing or a line connected thereto in his hand when the connection is released, the function of the separation can be impeded as a result of the elastic pretension.

In an embodiment, the present invention provides a plug connector part for electrical connection to a mating plug connector part, comprising: a housing, a contact carrier that is movable in relation to the housing and comprises: at least one electrical contact for the mating plug connector part, and a slider that is movable in relation to the housing and to the contact carrier, and an elastic element that is supported on the slider and on the contact carrier in such a way that the elastic element is tensionable by a displacement of the slider in relation to the contact carrier.
