ABSTRACT:
Coupling, comprising a first part (1) in the form of a male part and a second part (2) in the form of a female part, the male part can be brought into the female part and thereby form a ring shaped void (3) between the facing surfaces of male and female parts, which ring shaped void in the axial direction of the parts are delimited with an inner restriction (4) at an inner side and an outer restriction (5) at an outer side, and a feed-through (6) is arranged from the outer surface of the female part to the void (3), for injection of glue into the void, and a feed-through (7) is arranged from the void to the outer surface of the female part, for venting and leakage of glue when filling the void with glue, distinguished in that the feed-through (7) for venting and leakage of glue is arranged closer to the outer side of the void than the feed-through (6) for injection of glue.
