Abstract:
1. A connecting piece for a medical tubing, said connecting piece comprising a first unit and a second unit, said first unit comprising a first connecting element for a tubing element and a second connecting element for the second unit, said second connecting element comprising a tubular female part for engagement with the second unit and first sealing elements, said second unit comprising a tubular male part having a tubular portion fitting inside and surrounded by a portion of said tubular female part, and having a collar including a continuously extending delimiting edge defining a face on said male part, a connecting line between any two points along said delimiting edge in a peripheral direction of the male part being less than 90° in relation to an axial extension of said male part and said female part, said tubular portion of said male part having second sealing elements for cooperating with the first sealing elements, said first unit and second unit comprising respective separator elements, the first sealing elements and the second sealing elements configured for being mutually lockingly engageable by moving the male part and the female part axially towards each other, said mutual locking engagement establishing a lock, by which the first unit and the second unit are kept together with said tubular portion of said male part extending inside said female part; the separator elements comprising a face arranged on the female part and a face arranged on the male part, said faces being in abutment against each other when the first unit and the second unit are kept together by said lock, said faces being such that by a turning of the first unit in relation to the second unit an axially extending positive force component is provided for by said face on said male part riding on said face on said female part, said positive force component forcing the first and second units to disengage and to leave their mutual engagement by axial displacement; and the separator elements being arranged in relation to said sealing elements such that said separator elements are at an axial distance from said lock when the first unit and the second unit are kept together by said lock.
