Abstract

The present invention concerns a male connection part for connection with a female piercing member protection device having a longitudinal cylinder-like body having a longitudinal axis C, a first side and a second side, an outer and an inner surface, a barrier member arranged at the center of the first side of the male connection member, intersecting the longitudinal axis C, and a fluid communication channel extending from the barrier member of the male connection part to the second side of the male connection part, wherein the male connection part further comprises at least one turning grip protrusion to provide for an increased turning friction between the female piercing member protection device after assembly.

Claims

1. A male connection part for connection with a female piercing member protection device wherein the male connection part comprises a longitudinal cylinder like body having a longitudinal axis C, a first side and a second side, an outer and an inner surface, a transverse locking flange is located at the first side, a barrier member arranged at the centre of the first side of the male connection part, intersecting the longitudinal axis C, and a fluid communication channel extends from the barrier member of the male connection part to the second side of the male connection part, wherein the male connection part comprises a circumferential wall surrounding the first side, at least one turning grip protrusion arranged on the circumferential wall to interact with at least one turning grip groove on the female piercing member protection device,

the number of the at least one turning grip protrusion is more than the number of turning grip grooves

to prevent rotation in two directions between the male connection part and female piercing member protection device when the protrusion and groove contact each other.

2. The male connection part of claim 1, wherein the male connection part comprises at least three turning grip protrusions.

3. The male connection part of claim 2, wherein the at least three turning grip protrusions are symmetrically arranged around an outer surface of the circumferential wall.

4. The male connection part of claim 1, wherein the at least one turning grip protrusion runs substantially parallel with the longitudinal axis C.

5. The male connection part of claim 1, wherein the fluid communication channel is formed by the inner surface of the cylinder like body.

6. The male connection part of claim 1, wherein the transverse locking flange extends around the periphery of the outer surface of the male connection part.

7. The male connection part of claim 1, wherein the circumferential wall surrounds a second barrier member of the female piercing member protection device after connection of the male connection part with the female piercing member protection device.
