Abstract
Disclosed is a chain lock for round steel chains, comprising two lock halves, each of which is provided with a rear section (4, 5) that extends in the longitudinal direction of the chain lock (1) as well as coupling sections (6 to 9) that adjoin the ends of the rear section (4, 5). One respective coupling section (6, 8) is fitted with a locking pin (16) which extends perpendicular to a parting plane (TE) of the chain lock (1) and encompasses a web-like projection (22) at the free end (18) thereof, on the side facing the other coupling section (7, 9). The projection (22) borders a pocket that extends from one side surface (20) to another side surface (21) of the lock half (2, 3) and accommodates a forked leg (26) of the other lock half (2, 3), which conforms to the contour of the pocket (23). The pocket (23) has external, essentially rectilinear flanks (27, 28) which face the side surfaces (20, 21), the angle (W1) enclosed by the flanks (27, 28) ranging from 120.degree. to 150.degree..
