ABSTRACT:
To eliminate the necessity for a temperature-hardening cement to set the ular ends of paired discharge tubes into a plastic base, a holding element (7), including inwardly and downwardly directed barbs or tongues (8), is located within the base, the barbs or tongues engaging in depressions (3) or behind projections (3') of the pinch seal (2) normally formed at the end of the tubes. To additionally hold the tubes in position, a compression gasket (9) is interposed between a cover cap (6) and the bottom portion (5) of the base, the cover cap and the bottom portion being connected together by a snap fit.
