<p>An operator for a latch system. The operator has a main body, a control unit, and a retainer. The control unit has at least a portion that is selectively repositionable relative to the main body by a user with the control unit in an operative position on the main body to change the state of a latch system with which the operator is associated. A retainer is placeable in an assembled position on the main body wherein the retainer maintains the control unit in the operative position. The main body has a first shoulder, with the retainer element having a second shoulder. The first and second shoulders face and abut each other with the retainer in the assembled position to prevent the retainer from being moved out of the assembled position such that the control unit could be moved out of the operative position. There are cooperating surfaces on the main body and retainer which guide the retainer and main body each against the other to allow the retainer to be guidingly moved against and relative to the main body from a first position relative to the main body into the assembled position. At least a part of at least one of the main body and retainer is deformable and is deformed as an incident of the retainer moving from the first position into the assembled position whereupon the first and second shoulders face and abut each other to prevent the retainer from being moved out of the assembled position.</p> |
