A pump-motor assembly includes a housing and a lead protector sleeve to protect leads disposed along an exterior surface of the housing. The housing and the lead protector sleeve include first and second cooperating snap-fit connection elements, respectively, to secure the lead protector sleeve in position along the exterior surface of the housing via a snap-fit connection. The lead protector sleeve may include a first portion spaced from the exterior surface to form a conduit along the exterior surface to accommodate the leads, and a second portion extending from the first portion to engage the pump-motor housing. The second portion may include a projection or depression to secure the lead protector in position along the exterior surface of the pump-motor assembly via snap-fit interaction with the housing. In one embodiment, the second portion may include a resiliently deformable tab.
