Abstract: An in-line clamp (100), including: a base (200) having a bottom (202) that defines a bottom plane (204) and a ramp feature (210); and a pusher (300) having a cooperating feature (304) and a contact ridge (314) disposed opposite the cooperating feature. Movement of the cooperating feature along the ramp feature moves the contact ridge downward toward the bottom plane and away from the base in a clamping direction (510). The clamping direction forms an acute clamping direction angle (514) with the bottom plane. An adjustment mechanism (500) is configured to apply a push force (322) on the pusher to move the contact ridge in the clamping direction. The push force is applied in a push force direction (322D) that forms an acute push force direction angle (508) with the bottom plane. The acute clamping direction angle is different than the acute push force direction angle.
