Connector piece for a fluid flow system

Abstract

A pair of connectors comprising a female part (20) and a male part (1), the female part (20) forming a receptacle (22) having an outer wall (27) and an inner space (24) defining a central axis (26) and configured to receive and hold the male part (1) when inserted in an insertion direction into the inner space (24), wherein at least one locking tab (30) extends integrally from the outer wall (27) and has its free mating end (32) pointing in the insertion direction of the male part and projects with the mating end into the inner space (24) to engage with a projection (8) on the male part (1) to releasably lock it into the female part (20),The coupling end (32) comprises two locking teeth (34) that are spaced in a circumferential direction of the inner space (24) and are integrally connected by a radially extended bridge portion (36) that extends a radial distance greater than adjacent portions of the outer wall (28) of the female part (20) to form a clearance (38) between the female and male parts between the two locking teeth (34) to allow the insertion of a wedge-shaped release tool portion (54) by moving it parallel to the insertion direction in the clearance (38), thereby pushing the bridge portion (36) radially outwards to disengage the locking teeth (34) from the projection (8) of the male part.
