A releasable connector for connecting tubing such as used in fuel lines has a display member to indicate when positive locking has occurred. The display member member is attached to the outside of the housing of the connector. The display member has a strap supporting a cover portion. The cover portion has a pair of resilient flanges which are insertable into an opening in the housing of the connector. The flanges extend into a chamber to engage an annular ring of a conventional male tube end. The annular portion of the tube end displaces the flanges of the display member after passing through a locking member contained in the housing of the connector. In this way, the tamper indicator indicates that the tube end has been positively received in the locking position.

Releasable plug connector with mounting display

The present connector for liquid-conducting, plug-type connections consists of a hose nipple (2) formed on the coupling (1) and pluggable into the connecting end of a flexible plastic hose (3). The nipple has at its free end a conically widening, beveled plug edge (4) and an adjoining cylindrical shaft portion (5) with several truncated expansions (6) and (7), as well as an annular contact flange (8) at the end of the plug-in area (E) portion. The back side of the first truncated expansion portion (6) has a conical taper portion (9). Between the expansion portion (6) and the taper portion (9) an encircling groove (10) is provided, in which is embedded a gasket ring (11) circular in cross section. In order that the end of the hose or tube can be easily slipped over the nipple and the gasket ring, the surface (M1) of the first truncated expansion portion (6) outwardly at an angle .alpha. of about 45.degree. in relation to the surface of the shaft (5) and is oriented so as to provide a slight clearance (a) past the outer surface (14) of the gasket ring (11). The surface (M2) of the succeeding taper portion (9) has a significantly flatter angle of inclination .beta. of about 20.degree.-30.degree. in relation to the surface area of the shaft (5) and its rearward projection is tangent to the outer surface (14) of the gasket ring.
