The present invention relates to a connector (1) for hydraulic and pneumatic systems of the type presenting a hole (4) for the passage of a fluid and a seat (2) with circular development arranged coaxially with respect to the hole (4) of the connector and destined to house an annular gasket (3); the seat (2) seen according to a section coplanar to the axis (X) of the hole (4), is shaped as an open quadrilateral, with a base portion or base (20) essentially perpendicular to the axis (X) of the hole (4) and two walls (21, 22) defined by rotational surfaces; at least one of the walls (21, 22) is tilted with respect to the base (20), i.e., it is not perpendicular thereto, so as to define a tooth (23) delimiting the seat (2) and able to hold the gasket (3) stably inserted in the seat (2) itself
