Connection terminal, comprising - a housing, - a plug-in opening, which is arranged on the housing and into which a conductor can be plugged in a plug-in direction, - a contact element, which is arranged on the housing and with which the conductor can be brought into contact by plugging in in the plug-in opening, - a spring element, which is arranged on the housing and which is held on the housing by means of a spring body and has an elastically movable spring leg extending from the spring body, wherein the spring leg is designed, in a clamping position, to clamp a conductor plugged into the plug-in opening to the contact element, and - an actuation element, which is arranged on the housing and which, in an actuation direction, can be actuated to move the spring leg out of the clamping position, wherein the actuation element can be latched to the housing in an open position in which the spring leg is moved out of the clamping position, wherein, to move the spring leg, the actuation element acts on a distal end of the spring leg, said distal end being remote from the spring body, wherein the actuation element has a shaft having a head by means of which the actuation element can be activated and having a foot section that is remote from the head, wherein the actuation element acts on the distal end of the spring leg by means of the foot section, wherein the actuation element has on the foot section thereof an abutment projection, which, in interaction with a projection of the housing, delimits a movement travel of the actuation element counter to the actuation direction, characterized in that the actuation element has in the region of the head thereof a latching projection for latching to an associated latching projection of the housing in the open position, and in that the actuation element, in the open position, can be moved in a release direction transversely to the actuation direction with respect to the housing in order to release the latching between the actuation element and the housing. - a housing, - a plug-in opening, which is arranged on the housing and into which a conductor can be plugged in a plug-in direction, - a contact element, which is arranged on the housing and with which the conductor can be brought into contact by plugging in in the plug-in opening, - a spring element, which is arranged on the housing and which is held on the housing by means of a spring body and has an elastically movable spring leg extending from the spring body, wherein the spring leg is designed, in a clamping position, to clamp a conductor plugged into the plug-in opening to the contact element, and - an actuation element, which is arranged on the housing and which, in an actuation direction, can be actuated to move the spring leg out of the clamping position, wherein the actuation element can be latched to the housing in an open position in which the spring leg is moved out of the clamping position, wherein, to move the spring leg, the actuation element acts on a distal end of the spring leg, said distal end being remote from the spring body, wherein the actuation element has a shaft having a head by means of which the actuation element can be activated and having a foot section that is remote from the head, wherein the actuation element acts on the distal end of the spring leg by means of the foot section, wherein the actuation element has on the foot section thereof an abutment projection, which, in interaction with a projection of the housing, delimits a movement travel of the actuation element counter to the actuation direction, characterized in that the actuation element has in the region of the head thereof a latching projection for latching to an associated latching projection of the housing in the open position, and in that the actuation element, in the open position, can be moved in a release direction transversely to the actuation direction with respect to the housing in order to release the latching between the actuation element and the housing.
