Connecting piece for a tubing
First Claim
1. A connecting piece (1) for a medical tubing (2), said connecting piece comprising a first unit (3) and a second unit (4), said first unit (3) comprising a first connecting element (5) for a tubing element (6) and a second connecting element (7) for the second unit (4), said second connecting element comprising a tubular female part (8) for engagement with the second unit (4) and first sealing elements (9), and said second unit (4) comprising a tubular male part (10) with a collar (11 ) and second sealing elements (12) for cooperating with the first sealing elements (9), said first unit (3) and second unit (4) comprising respective separator elements (13), characterized in that the first sealing elements (9) and the second sealing elements (12) are configured for being mutually engageable by moving the male part (10) and the female part (8) axially towards each other for establishing a locking device (14), by which the first unit (3) and the second unit (4) are kept together;
- that the separator elements (13) comprise faces that are arranged on the female part (8) and the male part (10), said faces being in abutment against each other when the first unit (3) and the second unit (4) are kept together by means of the locking device (14), said faces being such arranged in the direction of the peripheries of the male part and the female part, respectively, that by a turning of the first unit (3) in relation to the second unit (4) an axially extending force component is provided for causing the sealing elements to leave their mutual engagement; and
that the separator elements (13) and the locking device (14) are arranged such that they are at an axial distance from each other when the first unit (3) and the second unit (4) are kept together by the locking device (14).

Abstract
The invention relates to a connecting piece for a tubing including a first unit and a second unit, the first unit including a first connecting element for a tubing element and a second connecting part for the second unit, the second connecting element including a tubular female part for engagement with the second unit and first sealing elements, and the second unit including a tubular male part with a collar and second sealing elements for cooperating with the first sealing elements, the first and second units further including separator elements. The invention is characterized in that the sealing elements include a locking device; and that the separator elements and the locking device are arranged at a distance in relation to each other. Good locking is accomplished as well as sealing of the joint without a risk of leakage and unintended separation of the two connecting parts; the lock, which is hence internal and protected, ensuring good engagement, while simultaneously the separator elements operate independently of both lock and sealing. Moreover, the sealing elements operate independently of direction and with little force for activation.
