## Abstract

Connection devices for a moulding core for producing a fibre composite component are provided. Such a connection device can include a base element for receiving a coupling portion of the moulding core for subjecting the moulding core to a medium, a clamping element for fixing and sealing the coupling portion of the moulding core on the base element, and a locking mechanism for locking the clamping element with respect to the base element and the coupling portion of the moulding core.

## Claims

### Claim 1

A moulding core assembly, comprising:
a moulding core for producing a fibre composite component for aerospace;
a base element comprising a receiving portion for receiving the moulding core via a coupling portion of the moulding core and for subjecting the moulding core to a medium;
a clamping element for fixing and sealing the coupling portion of the moulding core to the base element;
at least one sealing element arranged between the base element and the clamping element for sealing the coupling portion of the moulding core to the base element; and
a locking mechanism for locking the clamping element and the coupling portion of the moulding core, wherein the locking mechanism has a clamping device with a clip and a lever; and
wherein the sealing element can be compressed in a sealing manner on the surface of the coupling portion of the moulding core and on the surface of the receiving portion of the base element.

### Claim 2 (depends on 1)

The moulding core assembly according to claim 1, wherein the receiving portion of the base element comprises an external cross-sectional shape adapted to an internal cross-sectional shape of the coupling portion.

### Claim 3 (depends on 1)

The moulding core assembly according to claim 1, wherein the clamping element is displaceable in the longitudinal direction on the base element.

### Claim 4 (depends on 3)

The moulding core assembly according to claim 3, wherein the clamping element is capable of being displaced by the locking mechanism into a first position, thereby releasing the coupling portion received in the receiving portion of the base element, and into a second position, thereby locking the coupling portion in the receiving portion of the base element.

### Claim 5 (depends on 1)

The moulding core assembly according to claim 1, wherein the base element comprises at least one aperture capable of subjecting the moulding core to a medium.

### Claim 6 (depends on 1)

The moulding core assembly according to claim 1, wherein the base element comprises at least one connecting mechanism capable of transmitting electrical energy from an energy source to an electrical unit of the moulding core.
