Abstract:
1. Connector for pipelines, having a first and a second connection end, with the first connection end in the form of a base body including a first support body, the support body provided with a closure ring which is directly attached to the base body, the closure ring and the support body forming an annular space for the insertion or withdrawal of a pipe end, with at least one claw ring and at least one clamping ring provided to secure the pipe end, which is inserted into the annular space in a direction towards said base body, in a clamping manner against axially acting withdrawal forces, characterized in that the clamping ring includes resilient segments and can be axially displaced with respect to the closure ring, and in that the closure ring is provided with an inner circumferential step with which the clamping ring is axially secured, the step defining a recess in a withdrawal direction of the pipe away from said base body, further characterized in that upon axial displacement of the clamping ring in the withdrawal direction of the pipe away from said base body the clamping ring is drawn into the recess, and said circumferential step causes the resilient segments of the clamping ring to spring out into the recess, and wherein upon withdrawal, the inner circumferential step adjoining the clamping ring provides a stop for said resilient segments of said clamping ring against a return movement of the clamping ring counter to the withdrawal direction.
