ABSTRACT A lock follower, particularly a handle or pressure follower, comprises a hub part and an arm part. The hub part consists of a machined rod-like or tubular material and the arm part consists of a punched sheet-metal material. The parts arc rigidly joined together by flow of material from the arm part to a peripheral groove in the hub part. Preferably the hub part exhibits in the neighbourhood of the groove a portion of smaller diameter than the main portion of the hub but of larger diameter than the hole for the hub part in the arm part. Said portion is pressed so far into the hole in the arm part while deforming the material defining the hole that the arm part abuts an abutment in the hub part. Further, the portion of the hub located between the peripheral groove and the abutment preferably has axially extending ridges around the periphery thereof to facilitate flow of material and rigidly securing the two parts together in both axial and circumferential direction. The invention also concerns a method of manufacturing a lock follower from two parts of the above described kind.
