The connection means comprises a first connection means (18) mounted to the traveling body (7), and a second connection means (19) mounted to the conveying and driving body (15).

One of the parts comprises a connecting means (8) including a spindle (7), which connecting means in the coupling position (6) is in engagement with a mating connecting means on the other part.

The first connection means (9) and the second connection means 17 are irreversably non-releasably secured to each other.

A connector (300) is also disclosed.

The connector tube may include a connector arrangement such as threads (60) to facilitate connection to pipes.

The handle means may also operate to retain a connecting means.

The first connection means (9) and the second connection means 17 are configured to mechanically cooperate to form a releasable connection (7).

According to the invention, the terminal fields are contacted with a flexible or rigid external terminal means.

The invention is directed to an improved connection means for asensor.

Either the first connection means (18) or the second connection means (19) is adapted to move on a mounting body in such a manner that said means can follow the other.

Said operating means (16) comprises a slidable adapter means (17) leaving the service valve (13) unaffected when the gas connecting means (10) is connected to the connecting device (12).

The connecting means (10) connects the outlet port (27) of the first injection unit (3) to the inlet port (26A) of the second injection unit (4).

The watercraft includes novel means for connecting separate modules.

In the centre a connection (3) is placed over the whole length between the top connection (8) and the bottom plate (2).

The safety means comprise at least one connecting means forming a force fit.
