A female coupling clamp which is adapted to hold a coupling head of a male coupling element in an automatic or self-latching manner and to fasten itself in a component opening in an automatic latching manner. For this, the coupling clamp is equipped with at least three resiliently formed strip-type coupling arms which are connected to each other on one side. The respective provided fastening ends of the coupling arms comprise a radially outwardly open receiving groove for an edge of a component opening. A ball head is held in a receiving space with the aid of a neck portion which is similar in shape to an inverted truncated pyramid.

Coupling clamp

An extension adapter of a plug-in coupling, with which a free space between a male coupling element and a female coupling element can be bridged in a connecting manner and which comprises the following features: a male coupling end which can be inserted into the female coupling element, a female coupling end in which the male coupling element can be received and which is connected to the male coupling end via an intermediate piece, and a locking element which is displaceably arranged in the axial direction of the extension adapter and with which, in a locking position surrounding the female coupling end, the release of a male coupling element from the female coupling end is prevented.

Extension adapter of a plug-in coupling and associated production and installation method

A coupling element of a two-part plug-in coupling has a head section from which a female connection structure extends perpendicularly in an installation direction of the coupling element, with a locking web projecting inwards on an inner side so that a male bolt element can be inserted into the connection structure opposite to the installation direction and can be locked there, or a male cylinder-like connection structure extends so that the male cylinder-like connection structure can be inserted in a female receiving element and can be locked there. The coupling element has an integral locking structure which has a circumferential, or a plurality of locking webs which, together with the head section, form an installation gap for receiving the component, so that the female or the male coupling element can be locked in the opening of the component with a relative movement in installation direction between coupling part and component.

Two-part plug-in coupling for connecting components

An annular plug coupling which can be fastened within an opening in a first component and has the following features: a central coupling seat, in particular a ball socket, to which a coupling head of a second part can be releasably connected, and an intermediate ring that includes a plurality of curved, radially inward-extending first spring elements connected to the ball socket, and a plurality of curved, radially outward-extending second spring elements which are provided with a locking connection at a radially outward end such that the plug coupling can be locked within the opening in the component.

Annular plug coupling, and production method and connection method therefor

The plug-in coupling comprises a negative coupling part and a positive coupling part that includes a pin having a ball head. The negative coupling part comprises a coupling construction made of a first material for accommodating and detachably fastening the positive coupling part, and a retaining construction made of a second material, which surrounds the coupling construction, for fastening the negative coupling part to the second component, wherein the second material has a higher elasticity than the first material.
