Claim:
A connector impermeable to liquids ( 1 ) comprising a first connector part ( 3 ) having connector pins ( 2 ) and a second connector part ( 5 ) having bushings ( 4 ) matching the connector pins ( 2 ), with the connector ( 1 ) in a plug-in position being sealed from liquids accessing the connector pins ( 2 ) and the bushings ( 4 ) by at least one peripherally extending circumferential sealing ring ( 6 ) located between the connector parts ( 3 , 5 ), and the plug-in position being secured by a rotational, axially fixed threaded bushing ( 8 ), which is supported axially fixed but rotational on one of the connector parts and with an internal thread ( 9 ) thereof matching a holding thread ( 10 ) on the other connector part, at least one additional turn of thread or projection or threaded part ( 12 ) is provided in a loosening direction at a distance from an end of the holding thread ( 10 ), that cooperates with the threaded bushing ( 8 ) and matches the internal thread ( 9 ) of the threaded bushing ( 8 ), the distance (A) from the end of the holding thread ( 10 ) to the additional projection or turn of the thread or threaded part ( 12 ) is greater than an insertion depth of the connector pins ( 2 ) in the bushings ( 4 ), and the at least one sealing ring ( 6 ) for the two connector parts is arranged at a position at which, after retraction of the threaded bushing ( 8 ) loosened from the holding thread ( 10 ), it remains in a sealing position up to the additional projection or turn of the thread or threaded part ( 12 ).
