You can override the serialization for any TSOAPHeader class. Just override its ObjectToSOAP function. I came up with this:

unit Unit16;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms, WsSelfBookingService, StdCtrls,
  InvokeRegistry, SOAPHTTPClient, opCOnvertOptions, XMLIntf, XSBuiltIns;

type
  TForm1 = class(TForm)
    Memo2: TMemo;
    Button1: TButton;
    procedure Button1Click(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

type
 TSOAPCredentials = class(TSoapHeader)
 private
    FPassword: string;
    FUsername: string;
    FKeyClient: string;
 public
   function ObjectToSOAP(RootNode, ParentNode: IXMLNode;
                            const ObjConverter: IObjConverter;
                            const NodeName, NodeNamespace, ChildNamespace: InvString; ObjConvOpts: TObjectConvertOptions;
                            out RefID: InvString): IXMLNode; override;
 published
   property userName     : string read FUsername write Fusername;
   property userPassword : string read FPassword write FPassword;
   property keyClient : string read FKeyClient write FKeyClient;
 end;



var
  Form1: TForm1;

implementation

{$R *.dfm}

{ TSOAPCredentials }

function TSOAPCredentials.ObjectToSOAP(RootNode, ParentNode: IXMLNode; const ObjConverter: IObjConverter; const NodeName,
  NodeNamespace, ChildNamespace: InvString; ObjConvOpts: TObjectConvertOptions; out RefID: InvString): IXMLNode;
begin
 Result := ParentNode.AddChild('userName');
 Result.Text := FUsername;
 Result := ParentNode.AddChild('userPassword');
 Result.Text := FPassword;
 Result := ParentNode.AddChild('keyClient');
 Result.Text := FKeyClient;
end;

procedure TForm1.Button1Click(Sender: TObject);

var
 ws   : WsSelfBooking;
 Req  : pesquisarSolicitacao;
 Resp : pesquisarSolicitacaoResponse;
 Rio  : THTTPRIO;
 Cred : TSOAPCredentials;

begin
 Rio := THttpRIO.Create(nil);
 ws := GetWsSelfBooking(false, '', Rio);
 Cred := TSOAPCredentials.Create;
 Cred.userName := 'admin';
 Cred.userPassword := 'secret';
 Cred.keyClient := 'key';
 Rio.SOAPHeaders.Send(cred);
 Req := pesquisarSolicitacao.Create;
 Req.registroInicial := 1;
 Req.quantidadeRegistros := 50;
 Resp := ws.pesquisarSolicitacao(Req);    
end;

end.

results in this request header:

 admin
 secret
 key
