A helmet assembly includes a helmet having a stud, a chinstrap having a strap, and a connector attached to the strap. The connector includes a housing and an actuator. The housing has an underside with an opening sized to receive the stud through the opening into the housing. The actuator is movable within the housing between a first position in which the actuator engages the stud to retain the connector to the helmet and a second position in which the actuator disengages the stud to release the connector from the helmet. The actuator has a gripping portion extending outside the housing for operation by the user to move the actuator between the first and second positions.
