Maybe you are using a wrong subfunction number.
The following works (extract from a TP unit)

function Generic_winclip: boolean; assembler;
Asm
	MOV	AH, 17H
	INT	2FH
	OR	AX, AX
	JZ	@end
	MOV	AL, 1
@end:
End;

function GetClipboardDataSize(Format: Word): LongInt;; assembler;
Asm
	MOV	DX, Format
	MOV	AX, 1704H
	INT	2FH
End;

function GetClipboardData(Format: Word; var Data): Boolean; assembler;
Asm     MOV	DX, Format
        LES	BX, Data
        MOV	AL, 5
        call near ptr Generic_winclip
End;

Note that the data size can be too long. A sort
of bug that will last till the end of Windows

You can see it in action (from/to Win clipboard) in EDIT
