Abstract: In a quick connection device for piping installed with a checker (40), a connector housing (20) of a quick connector (10) is formed with opening portions (74) for inserting resilient legs (58) therein through the opening portions (74) in a direction perpendicular to an axis from leading ends of the resilient legs, and inserted portions of the resilient legs (58) are held inside the connector housing (20). The resilient legs (58) are resiliently deformed in an axially inward direction by an annular projecting portion on an outer peripheral surface of a mating pipe at insertion of the mating pipe, to unlatch latching pawls (64) of the resilient legs (58) from corresponding latch portions of the connector housing (20), whereby the checker (40) is allowed to be removed out of the connector housing (20).

Abstract: A fluid line coupling includes a receiving part and a locking part connectable to the receiving part. The locking part includes a plurality of elastically resilient spring tongues engageable behind an annular collar formed on a plug-in part that is insertable into the receiving part. A securing part includes a plurality of elongate securing arms. Guide elements are formed on the securing part and the receiving part that are engagable with one another to displace the securing part in relation to the receiving part. In a securing position of the securing part, each securing arm bears against a respective associated spring tongue and prevents the spring tongue from deflecting outwardly. In this manner, the plug-in part is secured by a very high pull-out force against being pulled out of the receiving part.

Abstract: The invention relates to a fluid line coupling which has a receiving part (1) and a locking part (15) which can be connected to the receiving part (1) and on which is formed a number of elastically resilient spring tongues (18) which are designed for engaging behind an annular collar (29) which is formed on a plug-in part (28) which is to be inserted into the receiving part (1). Also provided is a securing part (20) on which is formed a number, corresponding to the number of spring tongues (18), of elongate securing arms (22). Guide means (7; 24, 25) are formed on the securing part (20) and on the receiving part (1), which guide means (7; 24, 25) are in engagement with one another for the movement of the securing part (20) in relation to the receiving part (1). In a securing position of the securing part (20), each securing arm (22) bears at the outside against a respectively associated spring tongue (18) and prevents the latter from deflecting outward.

And, the resilient legs 58 are resiliently deformed in an axially inward direction by an annular projecting portion on an outer peripheral surface of a mating pipe at insertion of the mating pipe, to unlatch latching pawls 64 of the resilient legs 58 from corresponding latch portions of the connector housing 20, whereby the checker 40 is allowed to be removed out of the connector housing 20.

Abstract: In devices for fastening at least one object (3) to a support element (8), an engaging arrangement (6) or a fastening arrangement is present by means of which a connection to said support element (8) can be realized. The engaging arrangement (6) or fastening arrangement is mounted on an inner cage (5) that is connected via a number of straight linking parts (15, 16, 17, 18) to an outer cage (4), on which in turn is formed a holding arrangement (1) for the or each object (3). Good decoupling of the holding arrangement (1) from the support element (8) with respect to mechanical vibration is thereby achieved.

Abstract: A fastening arrangement comprises a fastening element provided with a fastening portion having a planar outer side surface, and a hot-melt adhesive that can be melted in order to fasten the fastening element to a substrate. The fastening element is provided with a receiving recess that is open in the direction of the planar outer side surface. A retaining structure is provided in the region of the receiving recess. The hot melt adhesive is configured as a compact whose shape is adapted to the retaining structure such that the compact can be connected to the fastening element. The fastening arrangement can thus be prefabricated without incipient melting of the hot-melt adhesive.
