A watertight inlet device for inserting a cable containing optical fibers into a chamber or a container, e.g. into a splice box. The device includes a metal solepiece for securing the strength members of the optical cable, and which plugs into and fixes to a tubular sealing body equipped with an external O-ring gasket and having its rear portion shaped to form a sealing stuffing box on the outer sheath of the cable. The rear of the nut of the stuffing box receives a clamp for retaining the cable. Once the device has been fitted, the resulting assembly is inserted into the inlet passageway until it abuts against a shoulder in the passageway. Then only the head of the securing solepiece and a groove in the body project inside the container, the groove then receiving a key or fork for retaining the assembly.
