A header (24) fabricated of a lightweight non-metallic material includes a pair of opposed ears (44) which are adapted for sliding mated engagement within a channel support (46).

On one side of a hub chamber (11) suitable for accepting a slip-ring seal (12), said housing has a suction chamber and on the other a pressure chamber.

A sliding rail type connecting slot (3) is formed among the lower blocking edge (2b), the blocking wall (31) and the outer sidewall (32).

The invention relates to a sliding plug (10) and to a sliding element (1).

A header (24) fabricated of a lightweight non-metallic material includes a pair of opposed ears (44) which are adapted for sliding mated engagement within a channel support (46).

The slip ring arrangement has at least one slip ring (81) and a sliding contact, which is arranged so as to be capable of sliding on the slip ring (81) and is a so-called brush (89).

The slipping bed is a folding slipping bed, and the folding slipping bed is formed by an upper bed (2.2) and a lower bed (2.1).

There are some connection keys and connection holes on the location ring.

The connecting pieces comprise vertical connecting pieces and horizontal connecting pieces.

Provided are a versatile connection device (30) for connection between a pipe (40) and a connection member (45) and a connection method using the connection device.

The connecting stay of the connection piece (1) takes the form of a connecting plate (6).

The compositions of the invention either do not contain or contain only low concentrations of a glidant.

The connection member comprises a connection plug (31).

A connection ring (34) is present in the connection tool (30) for connection with the outside.

The connection structure comprises a first connection component (30) and a second connection component (40).
